working with paint bucket?!

[s0311685]

Hope someone can help me with this:

I want to use the paint bucket in a way that when you ad a new layer (let say a picture of car) before the already existing background (also one or more layers), that when I use the paint bucket that the surrounding white area (from the picture of the car) is adopting the format and color of the background!

The first times I worked with the program, I managed to do this in some way. But after a while it didn't work for me anymore! Now, when I use the paint bucket (and I choose the color picker to select the layout and color of the background layers) he just picks the color I select (example one color blue) instead of the real background.

What am I doing wrong, did I do something wrong in the configurations of the program?

Thanks for helping!

If the car you are adding has an all white surround,

you can use the Magic Wand tool on the white,

and then press Delete on your keyboard.

If you're removing a relatively uniform background color, and the wand + tolerance settings are not doing a perfect job, then have a look at the Alphaspace plugin or the Grim Color Reaper plugin.
