I recently installed SMF 2.0.1 and used Colorizeit to change the color of the SMF Curve Theme. When I installed the modified theme and created a new topic in a Board with that theme, the email.gif was displayed as "broken". I used the procedure recently posted for a problem with the useron.gif and was able to correct the problem. I extracted the email.gif from the original SMF images/bbc directory and zipped it separately. I then used the url from the modified theme and processed the zip file. After downloading the new file I extracted email.gif and then replaced the "bad" file in the original colorized theme .zip and re-installed it in SMF. No more broken icon. I had to do the same thing for a number of themes with different color changes.
