As long as it's wrapped correctly.  #imageWithForm: expects an object 
that responds to the following messages:

- #width (the width of the image in pixels)
- #height (the height of the image in pixels)
- #asMIMEDocument (a MIMEDocument instance containing the appropriate 
raw data and mime type)
- #= (compare to another object; should return true if that object 
contains the identical image data, so you might use a primary key from 
your database or some such)
- #hash (a hash method to match #=)
