Hi Roger,
I frequently receive requests from members to modify their photos and update their profiles. As Chris said; "It's not the file size, it's the "pixel size" (the number of pixels, horizontally x vertically)."
Depending upon the files that members send me, I've modified their original files in various ways. Some samples are as follows: (90 x 76)...(90 x 67)...(80 x 80)...(70 x 80)...(64 x 80)...(59 x 80).
If you're still having trouble uploading an Avatar to your Forum Profile, after reading this information, please email me with a request to add an Avatar to your Forum Profile and attach the photo you would like to use to your email. I will return the original photo and the modified photo to you for your archives. You may find my email address by viewing my Forum Profile.
I hope this helps you.
