Changing background for a image

[jankratochvil]

I have in my Flash site imported images. In Flash I use blue background with gradient and I need to have transparent or other background of my images.

I tried it, but if I use in PS or FW Magic Wand Tool and erase the white background( what e.g. image has ), than the edges are unworthy, I mean edges are sharp with rest of pixels with different tints of primary white background color.

How can I make it?

Thanks

trace around the image with a 'pen tool' or the selection of 'marquee tools' to get a better selection or use the 'extract filter' or paint the selection with the 'quick mask' tool (q). The magic wand is tricky to use and can give you undesired results if you dont use it right.

basically what I am saying is you need to get a better selection of your image and erase the background with that selection. Consult your Help files with the different selection methods i noted above.
