i have a gallery page where each thumbnail opens a larger image in it's own pop up window. that part works fine onmouseup the new window opens to the exact size of the image it contains. ( i know somepeople find this annoying, but i need each image to be it's own object, trust me it doesn't suck.) except the problem is IE works but NS crops the image. the proportions are understood differently by each. so i need a code that will detect the browser when the thumbnail is clicked and open the image.html in a window that is one size for IE and one size for NS. i understand the seperate pieces of code involved but i am having trouble merging them. thanks
