Well, I've just finished redesigning my site,
A Different View, using the Post Slug addon.
The
ugly image ID in the URL is gone for good, and in it's place is a nice simple "post slug". :-D
And with a little help from mod_rewrite and php, I was able to keep all the old links to my site completely functional as well.
If anyone wants any of my mod_rewrite/php scrips, feel free to contact me.
