I'm looking for a way to extend the "caption" feature of images within blog posts.
My goal: insert one large image in a blog post, say a 250x400-pixel movie poster image. Instead of just one line of text below as "caption", I'd like to include a caption, then below that a row of small image buttons linked to different sites (say, IMDB - Amazon - other), then maybe one or two links to related posts). The main text of the blog would wrap around the whole image/caption/buttons/text box.
To put it another way, I'd like to have an inset box floated left or right within the blog post -- not just image+caption, but some combination of text, links and different-sized images. Newspaper sites use this sort of inset box all the time.
If I was creating the page from scratch, I would just float a div and put everything inside. But I'm not sure how to achieve this effect in a WordPress post.
