O.K., I would have posted it earlier but I was beginning to think I was the only pilgrim around here who couldn't upload his own avatar ;-) First I abandoned the idea of using colour image (obviously it can be done, but I was running out of patience) and like your fine effort, used a B&W file, I re-sized my image in PS to the required 125pixels x 125pixels at 72 dpi (no point using higher def for screen). Then instead of using 'export' or 'save as' in the pull-down file menu I used 'save to Web & other devices' as suggested by Todd, and made sure I was saving as 'Avatar' in the 'User CP' - it is easy to confuse the 'Profile picture' which requires an even smaller file size, with the 'Avatar' - thanks Sug for reminding me of this. Thanks for everybody else's suggestions too. Brian, I think I managed to save as a JPEG too, using this method...
