Yea, we figured it out. Your profile image file cannot be bigger than probably 100k. My file was 122k and that is why it was error’ing out. By happenstance, we reduced it to 69k and it uploaded with no problem. I can see why you want a small image size for your profile pic as a forum page with lots of posts would take forever to load otherwise. So, mystery solved, keep your profile picture file size below 100k and it will upload.
Keith will have to add changing the documentation on the profile page to note the file limit -- unfortunately, that is not an easy fix as you have to go into the guts of the programming of the website to find that. Put that at the bottom of your list, though, Keith as now we can easily help people having trouble with it.
So, I picked the pic that Keith took at Christmas with my superheros giving me hugs. I was going to photoshop Keith in to complete the pic, but didn't have time. (Keith thanked me). :-)
