Merge pull request from Carreau/ja...

Merge pull request from Carreau/ja Improve Image format validation and add html width,height This addresses the first two bullets of Validates first argument to constrain format to png, jpeg, Lets user specify width, height, or both and emits appropriate html I introduced a couple of class constants to minimize the number of times I saw 'jpeg' and 'png' and document the _ACCEPTABLE_FORMATS. I added one real jpeg image to the test directory and one zero-length gif file to survive the file not found error in super() Closes Add `assert_is_none`, `assert_is_not_none` to `nose.tools`
