I'm trying to upload a new pic, though when I do so, it states that I can't upload it because I would exceed my file space and to delete some files,
but I can't find anything to delete. I've already deleted my old pic and I haven't uploaded anything else.
Upload Center v2.0 for ATS Members
Adding that file to your list of files would exceed your maximum allowable storage space.
If you would like to add the file, please delete some of your existing files.
I have never used anything other than the ATS upload space except a few years ago when I tried Photobucket.
I've been using my upload space all week with no problems at all, and I probably have over 500 images stored on the ATS server. (I use a lot of pictures in my posts)
Perhaps you need to go to the ATS store and increase your upload limit.
