Warning: Division by zero during photo upload

[skidpics]

Turned my java uploader off to bulk upload some files from some directories and getting error:
Warning: Division by zero in /home/vande11/public_html/PIQUESHARE/gallery/image-inc.php on line 311

Error creating thumbnail! Error code: 1
Command:
"/usr/local/bin/mogrify" +profile "*" -size 0x100 -quality 80 -geometry 0x100 '/home/vande11/public_html/PIQUESHARE/gallery/data/506/thumbs/A_Dog_Day_Afternoon.jpg'

Can someone shed some light on this?

Does the photo upload if you use gd2 as your processor. Division by 0 means you have a setting empty in your upload options say thumbnail size or more likely there was a permissions issue and we could not process the file.
