Thank you very much for the response. Your code looked eerily similar to the code I was already using, but I plugged your code into a fresh project and it worked. It baffled my mind. I went back to my project and I got the same issue I was seeing before--the bitmap data would return 0 for both width and height. The flex debugger showed "Error #2015: Invalid BitmapData." for both getters. I assumed it was due to the 16.7 million limit (which doesn't seem to apply to bitmaps created by loaders) because I consistently saw the issue with images over that size. On a whim I tried our project without the debugger (just a normal run) and it worked! If that isn't crazy enough, I started noticing that the longer I used Flex builder the more common the issue became--that is, images at 13,000,000 pixels even started reporting 0 width and height (and the invalid bitmap error in the variables debugger view).
Thanks for taking the time to send your code and prompting me to look deeper.
