CDWC, I saw your website and I'm quite sure that what's happening to you is that you upload a picture that is too big. You have set the max. size of the pictures the users can upload to your site and when it's too big, you can find this photo in admin, but it will always be shown as white.

What you need to do is to delete the photo, resize it and upload it again.
See in admin, advanced settings the max size. Normally it's 450x450 px.
