I think the best way is to resize image without error confirmation. Simple add: :resize_to => [50,50] to the has_attachment. Or if you really want to check size, then you may use validate method, and check for the if width > your_width_max and height > your_height_max

Thanks for what, what was the solution... I still don't see any way to find out the dimensions of the original image, nor can I find information anywhere about how to get the original dimensions, just using "width" doesn't work.
