Javascript Help or Ideas

[FMRock]

Im looking for a javascript that will pop open a window, but I want the window to exactly fit the image. All of the images are different sizes and dont want to have to set the size for each one.

I found online that will do this, but does not work in Netscape.

Here is the one I found.

Anyone got any ideas?

Thanks.
