Unable to attach a screenshot to the forum thread

NOTE: I've attemped to attach a JPEG screen shot (252kb) and your form says it's an invalid image file.  I tried a PNG same thing.  What's up with that?

If possible please provide us with a bit more information about this case.

What browser do you use?

Is this related to the initial screenshot attachment (1) or to the image embedding within the post body (2):
