Well do you want to use the same photo per user (like an avatar) or a different photo for EVERY post?
I made avatars very easy by adding this code to the index.php
<img src=”https://yoursitehere/imgdir/<?php the_author() ?>.gif” id=”author_icon” align =left />
by having the authour upload an image that is saved as the author’s “login.gif” in the img dir. I’m sure it wouldn’t be difficult to do by catagory either if you chose.
just replace <?php the_author() ?> with <?php the_category(‘, ‘) ?>.
rename your images accordingly.
It’s a bit ugly but it does the trick if that is what you are looking for.
I’d post a link to my blog and show you but my blog is mostly for familial consumption and I am still not done with all my modifications. Work in Progress, so its not shown till it’s done. ??
