There are several tabs on the options dialog. Click one to
see the properties in that section. They are:  JPEG/PCD,
Animated GIF, Extensions, Copy/Move/Delete, Viewing,
Others 1, Others 2.
 

 
JPEG/PCD
Click on the Options Menu, then click Properties. If the
JPEG/PCD section is not showing, click its tab at the top
of the box.
 
The top half allows you to select whether to load JPEG
images as grayscale, which is faster. Click the check-box
if you want to use this option. Click it again to un-set
the option.
 
The bottom half allows you to choose the size at which
Photo CD images are loaded. Click one of the option
buttons to make your selection.
 
When you are done, click OK at the bottom of the dialog.
To exit without making any changes, click Cancel.
 
 
Animated GIF
Click on the Options Menu, then click Properties. If the
Animated GIF section is not showing, click its tab at the
top of the box.
 
Some option buttons allow choice of several setups for
animated gifs. The default is to show animation. You
can also choose to show only the first image in the
gif, or to extract all the images into a directory on
your hard drive. If you choose the last option, be sure
to type a directory in which to place the images.
 
Below the option buttons is a check-box you may click
if you want to show transparency in non-animated gifs,
as well.
 
When you are done, click OK at the bottom of the dialog.
To exit without making any changes, click Cancel.
 
 
Extensions
Click on the Options Menu, then click Properties. If the
Extensions section is not showing, click its tab at the
top of the box.
 
Here you can choose which file types will be automatically
associated with IrfanView. Those files will show the icon
for the viewer next to them in file directories; double
clicking the file name will launch the viewer, with the
file already loaded. Click any of the check-boxes next
to files you want associated with IrfanView. If you want
all of them associated, click the Select all button below.
The Clear all button removes all the associations.
 
At the bottom of the selections area is a box for
entering other file extensions you want associated with
IrfanView. Click the box to make it active, then type
in the extensions, each separated by a single space.
 
Below the selections area is a box you can click to use
thumbnails for loading bmp images. It is checked by
default. Click it to remove the option.
 
The Advanced button has some choices for Windows shell
operations. Click the button to access these options:
Add IrfanView To Send-to Menu, and Add Open-browse to
Shell Menu. Check either or both boxes, the close the
dialog, or exit with Cancel.
 
The Set Icon button allows you to choose a different
icon for IrfanView. Click the button to see several
choices; click one of the option buttons to choose
that icon. Click OK to finish your choice, or Cancel
to exit without making any changes.
 
When you are done, click OK at the bottom of the dialog.
To exit without making any changes, click Cancel.
 
 
Copy/Move/Delete
Click on the Options Menu, then click Properties. If the
Copy/Move/Delete section is not showing, click its tab at
the top of the box.
 
Several sections: the first allows setting of a default
directory for copy operations. Type in a directory, or
click the browse button to look through those on your
hard drive and select one. If you click the check-box
below, IrfanView will ask your permission before making
any copies.
 
The second section is used just like the first, but
allows setting a default directory for move operations.
Click the check-box to have IrfanView ask permission
before moving files.
 
The third section has several check-boxes that refer
to delete operations. You may choose to have IrfanView
ask permission before deleting files, send deleted
files to the Windows Recycle Bin, and jump to the next
file after deleting one. Click any or all of the boxes
to select these options.
 
When you are done, click OK at the bottom of the dialog.
To exit without making any changes, click Cancel.
 
 
Viewing
Click on the Options Menu, then click Properties. If the
Viewing section is not showing, click its tab at the top
of the box.
 
The top half of this dialog has several options. The
first is View all files in directory. Click this to
have the viewer display all file names, even non-images,
in each directory. If this is un-checked, only files
compatible with IrfanView will be displayed for Open
and Save operations.
 
The rest of the options affect the display of images.
They have no lasting affect on the image, unless you
re-Save it.
 
The next option sets the Zoom factor for Zoom in and
Zoom Out. The default is 10%, which is the amount of
size increase or decrease each time you zoom the image.
Type a new number in the box to change this amount for
more zoom or less.
 
The next option is Always 'Fit To Desktop' for big images.
Click this to have the viewer reduce oversized images
until they can be seen fully on the screen. Images smaller
than the screen's size will not be changed.
 
The next option is Use 'Resample' function for 'Fit To
Desktop' and Fullscreen mode. Click this to have the
viewer display the best possible version of an image,
whenever you put it in Fullscreen or Fit To Desktop mode.
 
The next option is Remember the last window position.
Click this, and each time you open the viewer, it will
be positioned on your screen wherever it was when you last
closed it. This is handy if you always want it to appear
at a specified location on your screen.
 
The bottom half of this tab contains options for the
Fullscreen mode. The first is a set of option buttons:
Show images with the normal size, Fit to screen larger
images only, and Fit to screen all images. Click your
choice; Fullscreen mode will display the images as you
instruct. The next option is Hide mouse cursor. Click
this to prevent mouse cursor (that arrow) from showing
on the screen while the images are displayed. The next
option is Show image filename. Click this to have the
name of each image displayed on the screen, along with
the image. Below this option is Show transparent. If
this is un-checked, the filename will appear in a small
box; useful to pick it out against images that fill the
screen. Click the box and the filename will be shown
without the box.
 
When you are done, click OK at the bottom of the dialog.
To exit without making any changes, click Cancel.
 
 
Others 1
Click on the Options Menu, then click Properties. If the
Others 1 section is not showing, click its tab at the top
of the box.
 
Various check-boxes allow access to a variety of options;
click any or all that you want to select them. They are:
 
· Use Undo option: (highly recommended!) Unchecking
   disables this function of the edit menu.
· Ask to overwrite for Save and Save As: checking will
   make the viewer ask permission before it destroys
   an old file in favor of a new one.
· Display file dialog for File > Save: when this is
   checked, clicking on Save will bring up the standard
   dialog, through which you can choose a directory in
   which to save the image. If you know the images will
   need to be saved back to the same directory, uncheck
   this option. Clicking on Save now will simply resave
   an image in place of the original. Note that this is
   only for Save. Clicking on Save As still bring up the
   dialog box.
· Only 1 Instance of IrfanView: unchecking will allow
   the viewer to open more than once at the same time;
   this is useful to view similar files at the same time,
   or to hold one file for a moment, while you look for
   another; checking the box will prevent more than one
   instance of the viewer at any time.
· Ask to Rename Incorrect Extension: while loading a file
   which has had the name given an incorrect extension,
   IrfanView will ask permission before changing it. If
   you answer no, the file will be loaded anyway, but with
   the incorrect extension still attached. Answering yes
   will change the extension as it appears on the hard
   drive. If you uncheck this box, the viewer will load
   the file without making any changes.
· Use flat toolbar: when checked, the toolbar appears
   as a two-dimensional set of icons; when checked, the
   buttons appear as raised, three-dimensional images.
· Don't notify if end/begin of directory is reached:
   you are browsing through a directory's images, using
   the spacebar to move to the next image; when you reach
   the last of the images in that directory, IrfanView
   asks if you want to jump to the first again; checking
   this option will suppress the question, and just go
   right to the first image. The option also affects
   browsing backwards, using the backspace; then the
   option refers to jumping to the last image in the
   directory again.
 
There are also two buttons, for further options:
 
· Clear MRUDs list: clicking this removes all the
   names from the Most Recently Used Directories list;
   this option may be used at any time.
· Create Desktop Link: places an icon on your Windows
   desktop that can be double clicked to start the
   viewer.
