I bought a CD-ROM, The World of Patterns. It’s supposed to work on ‘Any computer with an Internet browser and a CD-ROM drive’. Guess I don’t just have any computer, then …
The disk — an interesting mathematical/artistic study of patterns — is arranged as a tree of HTML files, with internal links and images. This is how the folders appear on my computer:
│ ├── islam
│ ├── preislam
│ └── pstislam
│ ├── latt
│ ├── other
│ └── quilts
│ ├── modern
│ │ ├── large
│ │ ├── patch3
│ │ └── patch4
│ └── usa
All neatly lower case, as one might expect. Unfortunately, the internal links are hard-coded to access links such as /art/Islam/over.htm, and Linux, being good and literal, can’t find the upper case ones.
Unfortunately, the majority of computers quietly ignore the case of letters on removable media. Linux’s insistence on being correct is at odds with what is generally considered useful. But there’s a way around this. You can give the mount command options to tell it to be more chill about case:
sudo mount -t iso9660 -o loop,check=relaxed,map=normal,norock,nojoliet disk.iso /mnt/scratch/
This works for me quite well:
The CD-ROM is interesting, if a little dated. The author has gone on to produce the website tilingsearch.org, a huge database of historical tile patterns.
Probably best to retire my ad hoc image rollover in wordpress, as Ultimate TinyMCE has it covered. Sure, it’s a plugin, but it makes it so much easier. After uploading your two images, select an image and put the two URLs into the Mouse Over/Out fields:
Easy! And no digging into the page source, either.
If you’re trying to change the header image, and the old image seems to be stuck, make sure you turn off WordPress Super Cache before you change the image. Before you restart the plugin, make sure you delete cached files, or the old header will come back and haunt you.
I’m seeing quite a bit of traffic to this post. I suppose I should explain that this was a quick hack to see if I could get image rollover to work on a friend’s wordpress.com hosted blog (and no, I couldn’t). This little example doesn’t do preloading, either, and I really don’t have any intention to develop this further. Sorry …

This does not work on wordpress.com hosted blogs; it gets stripped out.
Update: You probably want to install the plugin Ultimate TinyMCE, which does the job rather well.
