Perhaps this is an exchange-wide issue, but I keep getting "For security reasons, framing is not allowed; click OK to remove the frames." when trying to upload a picture to my question. Clicking OK does nothing, and the upload box disappears. Is there a way around this, or is this a bug, or this an issue on my end?
There is a size limit to uploaded images - 2MB.
Make sure the image is less than this and you shouldn't have a problem.
The issue is complex, and essentially stems from the web server rejecting uploads of a certain size.
