After seeing so many people complain about Drupal's theme engine and it's inflexibility, I decided to try for myself and convert an existing Nucleus theme to Drupal. I used bluemarine (phptemplate version) as a baseline.
1. Getting the basics done is pretty simple. It's easy to setup a container and set the global look and feel.
2. The problem is when I tried to theme items like navigation. I found that even ul and li styles are defined in a way not easy to change.
3. The biggest issues is when I tried to split out things like "date posted," "posted by," and "read more" (which I mentioned elsewhere.
4. I figured I would have to heavily edit the style.css but it turns out I had to edit page.tpl.php, node.tpl.php, block.tpl.php, and comment.tpl.php. That's pretty much each major theme file.
Just started playing around with Drupal and have a site mostly up and running. I decided to use the Slash theme posted here for the site, which looks fine for the most part, but doesn't display the user picture in nodes and comments. So I wanted to edit the code to do that, but I'm not sure how I can get the user picture for the author of the node/comment. Any help would be greatly appreciated.
