[Bug] Rebuilding thumbnails
 

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

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. :eek:

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.
