Wanted to post a follow-up here about the problem I experienced in case it helps anyone else.

I actually had two problems in my theme – one was I was using a css class that was in conflict with one in wp user front end pro. The class in question is .button. Normally I don’t think it’d be a problem, but I had a z-index applied to my version and that was the problem.

In addition, I had a function to restrict subscribers from accessing the dashboard. Without access to the dashboard the upload image functionality doesn’t work.

Hope this helps someone.

I’m having the same problem with image uploads in IE.

Some more details:

• Running wp 3.4.1
• If I switch from my custom theme to the twenty-eleven theme the upload works fine in both IE 7 and 8.
• In my custom theme the attach image button doesn’t work. It simply goes to “#” (clearly a javascript problem). It does, however, work in chrome and safari.
