I use Photobucket and all my photos (both from scanned wet film slides and my Canon 450D) are uploaded at 1024x800 (or thereabouts). But I have always had trouble producing an Avatar of the correct size.

In my Control Panel - Profile - Edit Avatar - I have several options to use to upload pics from various sources. None of them seem to work for me.!! I know it is me as I can see some really good Avatars on here and I would also like to post one!!!
I understand the dimensions must be 120px X 120px with a max file size of 60KiB. But what does this mean exactly - or even roughly?
I hesitate to say this but my 6 year old granddaughter has taken me to places on my PC that I never knew existed.

I scan , therefore I am.
