need help with wordpress
 

Hopefully someone could shed some light on the following:
I would like to link a post title to an an external url like you would in a link list.

I would also like to link a thumbnail to a single post.
For example, if I click on an archive month that then displays posts to match that month, the body of the message contains an excerpt of the full post and a thumbnail.
What I want to do is click on the thumbnail, and go to the full post. The only way I see to do that now is to click on the post title.

Would the thumbnail change with each post, or would it just be a graphic like an arrow or something?

If it's just a static graphic on each post that can be easily done.

Each post has its own model thumbnail.

I have found a solution for the first part, linking the post title to an external url by using custom fields.

Linking the thumbnail image to a post, still looking for a solution.
And BTW these are 2 different blogs, one is all text based and the other uses model thumbnails.
