Title: imageview is empty with invalid image from network

the image will be processed and displayed only if the response data is a valid image.

case:
if the server (Apache for ex.) reply with a forbidden (or not found) page (html) the nsimage is 0x0 and the imageview will be empty.

expected:
the initial image shoud be still shown.
