I'm having a problem similar to this one.. is there a way to get the height of an image that is being loaded?
I looked to be able to do this in the asp script I have generating the XML document, so I could have this in the XML, but I couldn't figure out how to do it. I figured I didn't need the width or height because the image could be scaled, but it turns out that I do need the height. Anyone know how to do this or is able to point me in the right direction? Thanks..
