Can't upload maps

After having played a couple games on here, I'm looking to start my own campaign. Problem is, I can't use the maps I made. I can upload them to my library just fine, but when I try to drag them to the page on the virtual tabletop the progress bar pulls up with a tiny bit of progress showing and never moves up (image attached shows how not-far it goes). The map file is less than 2mb, so that shouldn't be an issue. Currently using Firefox 1.7 if that makes a difference. Thanks for any help in advance.

I noticed you were on the art library popup window. You cannot drag images from the popup window the the page. It shouldn't have a progress bar at all. It should prevent you from doing so via a circle with a line through it. 1) Close the Art Library popup window. 2) In the art library type in 'practice' and you should get your practice map. 3) Drag the practice map from the art library to the table. Let me know if there are any further problems. - Gauss

Ohhhh, haha, ok. I feel pretty derpy now, but thanks very much.

No worries, it confuses many. The popup window is for organizing the files rather than using them. - Gauss

Yes, I see that now. Thanks again.
