Parameter is not valid - may be 304 response issue for images and maybe more

In reviewing Parameter is not valid errors in Exceptions table, it appears that this may be due to 304 responses.

In testing, I get this error on images returned. Using firebug to see what exactly comes back when these particular absoluteuri images are requested, I see that the first time I get a 200 and on a refresh I get a 304 not returned probably due to caching on the server end.

Debugging ImageManager, I think what is happening is that the image is actually not being returned, so line 96 is trying to do a FromStream call when the stream is a 0 byte stream (nothing returned so nothing there).

So need to look at how 304 respones are handled for images and maybe other things as well.
