Hi, Deb --
It sounds like you might be either uploading duplicate images, or images that appear to be duplicates to the system.
If it's the first thing, you don't need to upload an image more than once. Instead, when you're in the Image Details screen, you'll see an [add/edit] link to the right of the image. Click that and enter the profile ID in the "Add person or free-space profile:" box, scroll down and click the button to save changes to the image.
If it's the 2nd thing -- the image is very similar to another one you've uploaded -- follow the instructions in the message that comes up directing you to this G2G post up so that Chris can help get the image uploaded.
Please let me know if you have questions.
