uploading large images to albums times out (timeout)

[محروم.كوم]

Site is hosted on Godaddy shared linux. Not sure I have httpd.conf access. Have modified php5.ini with the following, yet does not solve problem.:

memory_limit = 256M
post_max_size = 100M
file_uploads = On
upload_max_filesize = 100M
max_execution_time = 2000
upload_tmp_dir = /tmp
max_input_time = 2000

I would like to make sure that 10 images with file sizes of 10MB or less (so up to 100MB) can be uploaded via the album upload interface.

Currently the connection times out with a 500 error with anything more than about 25MB of upload (about 3-4 images at >10MB each.

Is this a Godaddy issue or an HTTP transfer issue? Is there a setting I can inject into php5.ini to solve? There's no limit on ftp transfers, but I'm not sure what is involved in converting a script from HTTP to FTP. I'm sure its not an insignificant task to find out though.

TIA.
