WordPress.org

I read the wiki about the use of custom fields, but it didn't enter my consciousness I'm afraid. Could someone give me a live example of the use of these fields? And could they be used to attach images to words?
In my site I use 4 different icons to describe the kind of post it is. In MT I used categories to do this. I could do this now as well (although I didn't succeed yet), but perhaps a custom field is much easier?

i used meta post for movie i saw today and stuff...
but yeah, adding icons should be possible...

I read that part on the wiki-site, but I don't understand it.
* Is the key "The movie I last saw" and the value "Finding Nemo"?
* And what is the php-code you used in your index.php?

I tried it myself and it works, but partly. I mean, when I insert <img src="plaatjes/vergroot.gif"> in the keyfield or the equivalent (<img src="plaatjes⁄vergroot.gif">), and leave the value blank or just a whitespace, nothing happens. When I fill in ':' or something like that it works nicely. But when editing another post, or re-editing that last post, I won't be able to choose that code again, other than pasting it manually in the keyfield.

weird WP is supposed to save the values of the key...

How do you use this in your templates? I dont understand what the wiki says about that.

OK Here's How I Did It just now:
I made a post and created a "Reading" key in the custom fields area below the writing area of a post. In the "value" I put a book I'm reading.
I then saved the post, and then chose the drop down "select" to choose "Reading" from the "add a new custom field" and input a second book I'm reading into that value field.
So I had two custom keys there, both called "reading" with different values, a different book each.
On the index.php template I put this:

<?php the_meta() ; ?>
in the same div as holds the post title and categories the post is filed under, etc. I have it placed underneath all that stuff so that it shows up last.
I published the post and this is the output I got:
"Reading: Pendragon Cycle, Mansfield Park"
This is what it looks like on the Source of the web page:

<ul class='post-meta'>
