As many of you know, there is a long time issue with image caching. When you change a profile pic for example it may still show the old one.
There are several solutions available for this, unfortunately the best require rewriting a significant amount of code, which I would rather not do at this time.
However, I was able to make one improvement with the caching, that now, the issue should not persist for any longer than 1 hour after you change the image. I made another change that some people will see the change immediately, but thats a browser specific thing. So it will work for some and not for others,
