Images not loading when page accessed via LTM

Are you offloading SSL by any chance ? If so, you've probably got http:// links to the images in the page content, and this is best fixed at the webserver (by using relative URLs, not absolute ones), but can, at a push, also be fixed with the stream profile.

I suggest you right click on one of the broken images, and try and load it directly, to see what the actual error is.
