Hi. First of all, great plugin!
i installed it on my blog in combination with Nextgen gallery and everything seems to work as it it should, but when you try to like or send an image, it actually like and send entire page. He attach some other image from my gallery page together with only a name of my blog and some description. When i look on my Facebook recent activity, it shows me that i liked gallery page, not image. I don't know if i did something wrong but i suppose that plugin suppose to share concrete image. Here is link to my gallery page http://www.joskoibosko.com/?page_id=857
