Unable to create thumbnail or reduced size image

Whenever I try to batch upload pictures I get the following error:

Unable to create thumbnail or reduced size image.

Site Url : http://simpgfx.com/gallery
Login :  demo
Pass  :  demo

I've looked over this (Emoticon Permission) but I don't seem to understand what exactly I'm doing wrong.

Okay so I tried using IE with my demo user account and I clicked on Upload.

Now I get this as well : 

The previous file could not be placed.
You have successfully placed all the files. 

I only tried uploading one file, so therefore no files were uploaded =( I've used CPG in the past like 3 years ago and I could've sworn it was alot easier...
