Incorrect width/height returned?

It's normal, code use the file object value, which are the original image width and height.

Here's my version where I generate the derivative image and then use get_image_info() to grab the generated image width and height, as expected. I Also added mimetype value in token values since last version of Metatag Open Graph accepts them, and get_image_info() returns it so might as well use it ! Also supports imagecrop module.

Feel free to reuse/make a patch of it !

Edit : You need to edit Line 111 to " if ($images_style_sizes[$styled_uri]["width"] && $images_style_sizes[$styled_uri]["height"]) {", I used getimagesize() before get_image_info() )

Here's a patch based upon doubouil's code.

Needs to be rerolled.

Rerolled, and I added some comments.

After some testing, this appears to work reasonably.

Committed.

I just updated with rc1 my production environment where I initially made the patch, still works as expected (metatags returns imagecroped width and height). I'd say this issue is cleared for 1.0.
