I have just installed integramod 141 and created a few foto albums. now i want to fill them with pictures. when i upload one or two at the time it works fine, but when i want to upload a zip file (i have enabled zip in the upload configuration) i keep getting this message: Your file type is not allowed.

whatever i try it will not work.
