问题 I have one situation. I create a website. Then I put a tab that will link to Facebook authorization login page.

It seems to be working fine, except that photos are appearing stretched/distorted in the box (i.e. one at the moment is about twice the height it should be.) We've changed from the default box width, but even at the default this was happening with our pictures. Is there any way to fix this?

问题 I have a site where I need to manually specify the content (and Url since some parameters need to be added depending on which facebook share link i press) in the facebook share-dialouge.
