Hi, i just fixed the zip upload problem. In my case the zip was transferred using the "allpication/x-zip-compressed" mime type.

So i just edited line 351 of imagebrowser.class.php and changed it to:

$accept = 'image/jpeg,image/png,image/gif,application/zip,application/x-zip,application/x-zip-compressed';

line 355 should the look like:

if ($array[2] == 'application/zip' || $array[2] == 'application/x-zip' || $array[2] == 'application/x-zip-compressed') {

for me it solved all my problems.
