This page of the options dialog deals with memory and file options.
|Display Image Size||This affects the display quality of images shown
in the preview pane
by setting the maximum size of images shown. It has no effect on printing.
A low value means that images look worse (more pixelated) but use less memory.
A high value means that images display better, but use more memory. A value of 2048 uses 16 times as much memory per image as a value of 512.
|Maximum File Size||This affects the display of images in the browser pane, by limiting the maximum size file that can be shown. Files larger than the specified size are shown as "?".|
This affects how images are stored in memory. By default, images are stored in compressed form and are decompressed whenever a new image is needed (rotating images or printing).
|Retrieve images from disk as needed.||Image is not cached. Whenever a new image
is needed, it is retrieved from disk. Use this option in the following
|Cache compressed image||Image is stored in memory in a compressed format. Whenever a new image is needed, it is retrieved from memory. This is the default option and is usually the best unless memory is limited.|
|Cache uncompressed image||This is typically the fastest option, but uses a very large amount of memory. A 3.3 megapixel photo takes up 10 meg of memory. Only use this if the images are small or you have an enormous amount of memory.|
Tip: To check how much memory is being used by images, see the Statistics window.
