how do I make a specific color from a css image disapear so it becomes transparent. Example: I have a picture of this girl with her hand leaning on a text area. I took another picture of her hand and uploaded it with css. what I want to to is remove the white stuff so it looks like her hand is leaning on the text area.

Try this code in your head tag. It should take out the white bits; if it doesn't, you may want to erase them in a photo editor and make the background transparent.

<style type="text/css">
body{ filter:chroma(color=#FFFFFF) }
</style>

Of course, if you needed to remove a different color you could just change #FFFFFF to another color code. =)
