Thumbnail for each post, Easy view

I understand the first part you said, as I did that on the archives and category pages. But where can I find a category icon plug in?

I tried doing that…
found this one
http://ww.wp.xz.cn/extend/plugins/post-avatar/
it does not work for me. after activating the plug in and configuring the settings. The option will not appear in my write post page. I think that one does not work properly with WP 2.6

all the other ones I came across did not work…
are you familiar with a plug in I could use?

I tried that one already, even though it’s activated it does not show up in my admin panel in Manage or Settings.

now that category-icons plug in works.
Unfortunately it can only display an icon for the category, meaning the icons cannot be different for each post

I think

would be perfect but it does not work in WP 2.6 as far as I see
