I've set up an IDS at i.mudshark.org for images. It does a reasonably good job of resizing images, providing a gallery, etc. Although linking directly to the image cache probably isn't wise, as the links will all break whenever the cache is cleared.. Hmm.
I also cleaned up the CSS a bit to pad images and the post footer properly. I'm still using align attributes to the img tags, which the w3m tells me are deprecated. Oh well. Something to fix later when I'm not so clueless about CSS.
