i have some difficulties with the new Facebook like feature. usually, each one of my blog post has an image in it. when i use the facebook share feature everything is going well: it lets me choose as a thumbnail between the images embedded in my post and in the description it shows the entire first paragraph (or at least most of it).
recently i've added the new facebook like feature to my blog but i can't make it behave like the share feature - when i like a post it doesn't use the post embedded image as a thumbnail. i managed to to make it display a default thumbnail by inserting this to header.php -
<meta property="og:tag name" content="tag value"/>
however, this is is only a partial solution. is there a way to make it use the post image as a thumbnail?
in addition to the thumbnail issue, the like shown on my news feed doesn't grab the first paragraph as a description but only the 85 characters of it. is there a way to make it show the whole paragraph or at least more characters?
