Had same issue in IE7.
Have a look at Change set 7573 #7573
I edited two files (removed 1 comma in each file )and Gallery fully functional in Browsers. IE7, Safari 3.4, Opera 9.2 ,FF2.13 and SeaMonkey 1.1.18.
edited handler.js removed extra comma from line 99 (#6443 & #7573)
IE7 Gallery is working.
Thanks, Not quite the same issue, as its with all media types, but its similar enough. So checked \includes\media.php and debug, (extra ,) was present – edited as per Line 817 (#6443)
Have same IE7 issues, Seamonkey still fully functional.
Guess I need to scan through the JS files.
