 So I'm in a project where the defined thumbnail must always be bigger then
 a certain size, and my problem is whether I can filter to check the size
 of the image, using a filter on the ''update_{$meta_type}_metadata'', the
 function ''set_post_thumbnail()'', always return true, so my change is
 really small so the developer can filter and return false if it pleases;

 In my case I would filter that and the content on
 ''admin_post_thumbnail_html'' to Warn the user that he cannot set a
 thumbnail with this size.

 Check out the .diff, and if there any other place that I can change
 something, to make it better warn me.
