[Bug] Rebuilding thumbnails

KW802 · October 26th, 2007, 10:19 AM

After losing 500~ files this week I tracked down a problem with how thumbnails are currently being rebuilt.

To recreate...
1) Specify a size for your thumbnails (eg: 100 which equates to 100x100).

2) Upload a test image to your gallery that is smaller than the thumbnail size (eg: A smilie, icon, or other small graphic). I would highly recommend you upload to a category that is used only for testing (eg: I created a "Trach Can" category for misc. purposes).

3) Rebuild the thumbnails for the category that you upload the small image into.

The image will now be gone.

The problem...
1) When an image is uploaded that is smaller than the thumbnail size the original file name is populated in the ppgal_images table in both the 'filename' and the 'thumbname' columns.

2) In /admincp/vba_gallery_admin.php at around line 1900 when it is rebuilding the thumbnails it does a blind delete of the thumbnail file.
