How do I make control "buttons" look transparent in Javascript?

[DelphiCoder]

I wrote a gallery div where you see a photo, and at the top right corner of the photo I have images of arrows to go back and forth to see other photos, along with other controls.

My question is: My "controls" images (which I drew by hand) have a black background. Is there a way to make the background transparent so that all I see on the photo is the control itself? If this is not doable in Javascript, is it doable in Photoshop, etc, or some other technology? I really don't want to use Flash for this.

you might play with the css-transparency settings described here ... otherwise you could use a image processing software to create transparent images ... i think gif and png does allow transparent channels ...

kind regards

Thanks. I feel stupid. I did a search and found the answer on Google on how to make a GIF background transparent with "The Gimp". Now my photo browser looks semi-professional.
