Large image files (maps) fail to display after uploading, with no error

Description of problem: I am trying to create a world map for my players, but whenever I try to upload it (by dragging it from windows explorer into the roll20 interface), the upload progress bar indicates that the file is being uploaded, but no image appears after the upload. Additionally, a "broken image" icon appears in the thumbnail view of the campaign page toolbar for that page. All of the files I've had this problem with are PNGs. I created a video demonstrating the problem. Both files were created with the same program, but one is larger than the other. I don't know why the one fails to upload correctly. <a href="http://www.youtube.com/watch?v=M9eRXewQ2Qk" rel="nofollow">http://www.youtube.com/watch?v=M9eRXewQ2Qk</a> Steps to reproduce: Upload a large image file (not necessarily large in file-size, but large in dimensions). My files were 1000x800, 2000x1600, 900x720, and one file approximately 400x800. Observe that the image doesn't appear visible, I guess.

Files sizes seem to be fine.

Could you please send me a join link to your campaign via my inbox? Thanks. - Gauss

I sent you a link just in case, but I believe the problem has been resolved. When I tried to upload an example of one large file to an imagehost, the file failed to upload. It appears as though something is wrong with the file, not roll20. My mistake. Sorry for the false alarm. Editing the file and re-saving it in MS-Paint seems to have fixed it.

Ok, good to know. :) - Gauss
