In 3.2.1 without Adminimize (and with Adminimize < 1.7.23) editing images works just fine for me.
WordPress 3.3 is too new. Until I know all of the plugins I use actually work in 3.3, there is no way in hell I am updating a production site to it. At this point, I am even leery of updating my test site to 3.3 (for fear of ending up with a completely useless pile of code). When I get a chance, I will create another test site for 3.3.
