Hi Ben,

well the jpg will never work as it does not support transparency.
but the png should be all good (and the best quality option as it
supports partial transparency).

I may have not understood your problem, there are two different options
you may be looking to achieve. Can you tell me which?
a) You want to show an image that is round as the complete button, with
no button square border or text.
or
b) You want to show a button with a round image contained inside it.
The button still has it's square shape.

If a is your desired option, I suggest using a picture box (background
set to transparent) and capturing the click of the picture box the same
as the click of a button. Also set the cursor for the picture box to
the 'hand' as happens for a button.

if b, it should be working without a problem.

Does this help?
