OK; now the cropping-bars are removed, the image is being made correctly.
Which graphics format are you making? PNG or GIF ?

If GIF, the images should show with a transparent background on all browsers,
but there are licensing issues with using GIF.

If PNG, then only some browsers implement transparency; others do not.
So it isn't the image that is faulty but the web-browser.

To the general list is fine.
These are recurrent problems; it's good to have the solutions
in the list archives.

Hope this helps,
