Now I get it. Ok open photoshop (CS3 I am using at work and CS4 at home).
1: Open Photoshop
2: Open your background photo
3: Open the filigree
4: Choose the one you want (use the crop tool to crop it)
5: Drag and drop the chosen filigree into the background photo
6: Use the Eraser tool (Magic eraser tool)
7: using the tool click on the white parts of the filigree.
8: Keep cleaning it until you get rid of white background of filigree
9: Once done you can move the image (layer) anywhere in the background
10: Save the background and test
On the other note: The image background if litterly used is a bad idea as on slow connections your website will load in layers its like watching a movie with 1 frame per second.
Let me know how it goes
Best of luck
