Problem with GIF-Graphices

Hi.
I'm using transparent GIF-Graphics in my Shop in order to show my products.
Somehow the graphics are'nt shown transparent. What should be transparent is shown black. I tried to change in style.css and took a look in the sourcecode to know which class is used for the foto_listing, but it seems it's not possbile to use transparent GIFs without having the effect described above.

So maybe I'm doing something wrong... Does anybody know how to change?

Have a look on my shop @ http://www.fr-dieseltuning.de/shop/

that is something "funny" ....

i tested it and what i found was:
- uploaded some emoticon , gif format and that was showing fine!
- in photoshop created a gif file with!!! and Save for the Web as Gif
with and without Transparancy selected. ( Transparancy: included transparancy based on color opacity )

When i did not have Transparancy selected the gif shows fine... but with it it looks like the gifs on your site.

I am sure a real graphics designer knows why ;-)

and what is really strange... if u enlarge the picture by clicking the graphic in the article's details, the gif file is shown straight normal...
so maybe it's all just a matter of configuration?

ooh okay.. i have not seen it..
But i guess it musst be something in the GD imagecreate functions
that creates a file on the server from the original. not sure if that is "fixable" ...

Yes, it's problems with GD2 library in PHP. It works fine with .jpg and.png files, but have some problems with .gif files.

Hi There,

Is there already a solution for this? Now I need to convert all the transparent gifs and it looks so much nicer if your cart has an backdrop image.
Any direction where I should/could look for a solution?

You can do the conversion using the GIMP - http://www.gimp.org - to change transparent GIFs to transparent PNGs. Works here on my server (easyPHP).

Run the GIMP, File>Open and select the transparent background GIF. Then in the picture window File>Save As and _untick_ the "Select File Type (by extension). This gives you a dropdown menu of types and select PNG. It should automatically sense the transparancy in the GIF and apply it to the PNG.
