Image upload with broken thumbnail image

OpenEI users can upload images to the wiki by typing a new file name http://en.openei.org/wiki/File:My_new_file.jpg

However, due to a caching timing issue, right after upload, the 120px-wide thumbnail has not yet been created by the time the fetier cache goes after it.  Thus, the thumbnail appears broken.

Is anyone up for debugging?

For users uploading images, this can be fixed by forcing a reload of the page:

Windows: ctrl + F5
Mac/Apple: Apple + R or command + R
Linux: F5

 

Thanks!

Fixed!

Jhuggins and I did some close server analysis, and Jhuggins fixed this issue permanently on August 10th, 2012.  Uploads should no longer have broken thumbnails right after the upload.  Thanks for your patience on this!
