Purpose of the Mod

To make the the generation of thumbnails quicker and more flexible. Changes include:

  • A mod parameter lets you increase the file size limit (which is normally 1MB), since most servers seem able to process files of 2MB or more.
  • Process only the Mediatypes and tree that have been selected (I generally don't bother with censuses and documents)
  • Generate a list of new thumbnail paths and offer to display it.
  • Displays files that couldn't be processed (and offers to hide that list).
  • (VERY SIGNIFICANTLY) turn admin_generatethumbs into an include file that is included directly in admin_thumbnails.php, which used to invoke it through AJAX. Unfortunately, using AJAX causes some errors to be hidden and makes it impractical to interrupt a long-running operation.


Skip files larger than this size, in KB (defaults to 2000)
PHP crashes badly if it runs out of memory when trying to create a thumbnail, and the pristine code sets 1000Kb; that is, 1MB, as a reasonably conservative limit. I have found that I can get by with 2.5MB (2500KB) on my servers.
