I am using WLPG with a gallery script called Coppermine.  There's an option to use Web Publishing Wizard or the order prints option to upload my photos to my Coppermine gallery.  Lately, I have been having a hard time uploading photos.  The size of these photos start at 25KB but there are several of them to upload.  I can start the process of uploading using the order prints option.  I can get a number of images to upload before the process starts to hang and give me a weird message.  The message says this:

The printing company only received part of your order.  You will soon receive an email confirmation with details about your order.  The email contains contact information so you can follow up on your order with the printing company.

To me, it seems like there's some kind of timeout issue but I don't know.  I've contacted my web host and they said that it has to be something on the end of WLPG.  Can someone please lead me on the right path to getting this resolved? I am restoring a gallery and have loads of images to upload but this problem is making it impossible to do.
