Question

My app is posting to users’ Facebook walls, and linking to a page they have created. The page is in html. I’d like to be able to put a thumbnail of the page as the image on the wall post. I’m not sure whether this is possible or not. Anyone have any ideas?

If it helps, the page itself is stored as a series of ‘elements’… for each one, I know the size and position of the element, and the content (which may be text or an image). So I can pull all that in from the database.

I guess it would be sufficient to create a thumbnail using php at the point when the user clicks ‘Publish This to my wall’, if that’s easier than doing it on the fly – I can save the image and then link to it.

Any ideas?

Answer 1

I figured out how to do this. I used the PHP gd library, which allows you to create a base image and then add images and text. Works pretty well.
