Any Content With Image attachmentment times out

I have been experiencing this problem since I've installed/upgraded to Drupal 7.

I was using Drupal 6 with a site, and when it came to upgrading I decided to only migrate the User accounts and create the content from the beginning, as it was a large hassle getting modules to work with the new versions in Drupal 7 (some of which were integrated into core).

So, I copied the site and database into a subfolder, ran the successful upgrade onto that installation, copied over only the user tables into a new Drupal 7 Installation. I then installed some additional modules (one of which I believe is causing this conflict?)

Now that the background is explained: On pieces of content where I include a field for images, using the Drupal Core file/image module, I add the image, the blue spinning loading circle works but the file never posts (hence, the circle never stops spinning). If I try to save the page (something that has worked for me in the past), the result is a Session Timed Out (no response from server, takes too long, etc) by the browser.

Update: I thought I got it to work for a bit. I had a size limit set on the image (2048x1536). Once I took that off it no longer timed out. This makes me wonder, is this a drupal core bug? It shouldn't time out if the file/image is not the right size/format, correct?

UpdateI've done all the testing that I can, and I am still unable to upload the files. Ive switched the type between public and private, I've removed the file field completely from the content type (which results in it being able to post). I've now noticed that file upload works, but an image upload does not.

Can anyone help me out?

My server is a Network Solutions shared unix hosting package. MySQL 5.0.91 and PHP 5.2.17, 128 MB memory limit set
