After experiencing a multitude of problems on this site (and others) with pictures, thumbnails, and other assorted problems, etc, I was getting pretty frustrated.

I read through most all of the posts regarding the issues I was having with only partial luck.

Well it's not HDForums fault, it seems that Internet Explorer 11.0 is the culprit. Of course there is a relatively easy fix. Go back to IE 10.0 (or 9.0).

Do the following:
1-Go to Control Panel
2-Choose Programs and Features (Windows 7)
3-Click on View Installed Updates
4-Scroll down to Internet Explorer 11.0
5-Click on Uninstall

After it uninstalls, you will be asked to reboot, and after you do IE 10.0 or 9.0 or whatever version you upgraded from will be back.

Magically, all of my issues went away.

Hope this helps.
