First of all congratulations for this great script ...
I've got a question .. where are stored the files ? ---> ok found out
-> another question ... I've got an issue with big files .. everything is working fine with small files .. I tried so far files smaller than 10mb ... but tried also with a file over a 100mb it's uploading fine said 100% but then nothing is happening .. it doesn't give any url for the uploaded file or doesn't send any email... it just stops ! any clue ? (just to tell I change the max file size in the admin panel)
