I am trying to find a way to post an image along with a description to a Facebook page. The idea is for users to submit a photo and a description to a website. Once the image is uploaded the user can then share the uploaded image with the description they've added on to a Facebook page.
I'm not sure if this is possible to do. I guess it's something Facebook's Graph API might help or maybe something like from this question (Facebook share button and custom text) would be enough:
<a title="send to Facebook"
href="http://www.facebook.com/sharer.php?s=100&p[title]=YOUR_TITLE&p[summary]=YOUR_SUMMARY&p[url]=YOUR_URL&p[images][0]=YOUR_IMAGE_TO_SHARE_OBJECT"
target="_blank">
<span>
<img width="14" height="14" src="'icons/fb.gif" alt="Facebook" /> Facebook
</span>
</a>
