image request failed with error: Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0x8f9f900 {NSUnderlyingError=0x9a94cf0 "bad URL", NSLocalizedDescription=bad URL}

Answer 1

Your URL is malformed. Right now you have:

http:\\www.school-link.net\\uploads\\%@

Those backslashes should instead be forward slashes. Ex:

http://www.school-link.net/uploads/%@

Now you can append image_url to the URL, and presuming image_url doesn't cause the URL to be malformed, your request will go through.
