Hi all,

I need to remove the background of an image to place it over a background image within a webpage but need to completely remove the background so that only the dropped image appears and not the white square that surrounds the background. In other words lets use this as a working example. I have a banner background in Artisteer that I am using. I can insert an image from file, I'll suggest a car as an example. I can crop the image of the car using Paint but when I insert it into the web page using Artisteer I have the textured background with an image of the car with a white square behind it. I want to be able to simply show the car overlayed over the textured background if that makes sense?

Does anyone have any suggestions as to how to best achieve this?

Many thanks, Chris

it's not easy, cannot be automatized and most of all has to be done by hand.
You need to use the Lasso Tool in photoshop. Likely by zooming enough to gain a better precision.
The when you are done, cut the part you want to keep out, paste it in a new image and then zoom a lot to remove the pixels that for sure are still part of the background, one by one, using an eraser and hoping that the alpha channel, if any, is not too invasive

Isn't there some sort of 'Magic Wand' tool in photoshop to select similarly colored areas? (there is in Paint.net anyway - I haven't used Photoshop in a long time because it's so bloated)

It sounds like when you are pasting the image it is not pasting with a transparent background...but rather a "blank" background (which comes across as white when pasting). This might be a function of the programs you are using and/or image formats.
