png / gif background color

When I upload gif or png product images with transparent backgrounds, the images appear with a black background no matter what the image wrapper bg color is. I've scoured every css file and don't see background-color="#000000"

We will need to look int this with you further. I have created a support ticket for this. To view and edit your support ticket, log into your support history at:

I've run into similar problems, and although I have no idea if this is the answer you're looking for - what I did to fix my problem was add this:

background-color: transparent;

To the css item that it's doing this to. It seems to have worked for me, thought it might work for you.

Thanks, I changed the bg color of productCart, image, imageWrapper and img to transparent (one at a time and all at once), and the black background is still there. I then did the same thing again, only this time I changed the bg color to 00ff00. The black bg was still there on top of the green. I then tried redoing the image itself in Photoshop (instead of Fireworks), and ended up with the same result.

I have a transparent gif on a white bg in the body, and it displays fine. That's the only bg color called in any style other than lists in the menu css. Weird...

Transparent background now working, thanks Jimmy Wu! Here's the fix:

1) Upload the png / gif images WITHOUT TRANSPARENT BACKGROUND using the powerstore admin upload.

2) Go back and knockout the background color in Photoshop/Fireworks and overwrite the original png / gif file (from step 1).

3) Manually upload this file to the /Images/Upload/ directory (bypass the PS upload).

It seems that when you use the Powerstore upload in the admin area, something adds the black background. I'm sure WA will find a cure for this extra step.
