as I don't know if it is an issue or not, I prefer to post here before.
with upload tab, you have following url :
[site_name]/zp-core/admin-upload.php?page=upload&tab=images (jQuery)&uploadtype=jQuery
and
[site_name]/zp-core/admin-upload.php?page=upload&tab=images (http)&uploadtype=http
I don't know if space in url are valide or not
