WOOHOO!
I am *SO CLOSE* now, I can taste it!
I made the change to image_utils.php and now when I click on auto_thumbnailer, I get a dialog "search for missing thumbnail". I do the search, come up with a list, but when I try to process the list, I get this error:
Create thumbnail for: 7412 (7412.jpg) ....
Fatal error: Call to undefined function: imagecreate() in d:\www\imageshare\imagevault\includes\image_utils.php on line 65
Second issue is that when I upload an .jpg image, it doesn't automatically generate a thumbnail. I suppose the two issues are related?
Getting closer,
