OK, this works great when I run the application locally, but when I
upload to the server and run it from there the images aren't being
resized (no error message - nothing happens). I tracked the problem
down to:
var img_width:int = img.content.loaderInfo.width;
var img_height:int = img.content.loaderInfo.height;
These statements work fine when running the Flex app locally, but
they cause the function to stop execution when executing the Flex app
from the web server. If I place an Alert before these statements it
displays fine, but if I place an Alert after these statements it
never shows up.
Any ideas why the content.loaderInfo would work fine locally but end
up null or undefined when running from the web server? Why the
difference? What can I do to ensure this works on the server?
Thanks!
