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 circumstances:
  • Memory is limited
  • Image files are large
  • Using uncompressed image files such as TIFF or PSD.

If using this option, it may be best to copy scanner or camera files to a temp directory.  See Camera and Scanner/Twain pages.

  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.
