Trouble uploading pictures

Hi, I'm running Elgg 1.7.11 and PHP version 5.2. When trying to upload pictures I get one of two errors; eiter the I/O error or the HTTP error. I also get the red notice at the top of the screen that the administrator has not yet set album settings. I tried installing the tidypicsext package thinking that would give me a different uploader but no dice. Maybe I misunderstood the plugin. I'm running tidypics 1.7.0 because the most recent version gave me the gatekeeper error.

Anyway, I'm stuck. If anyone can help that would be great. I'll leave both plugins enabled on the site if you want to see it first hand.

Thanks in advance...
