Hi Zaphod, In my opinion, you will be better off using external images - meaning that you serve your own copy of the images you want, but alongside the tiddlywiki, not inside it.
I think this is better becasue a) it's a bit rude to load other people's resources routinely (I know this isn't a huge concern these days) b) you won't have to constantly check to make sure the images are all still there and haven't been moved and c) it makes what you're trying to do easy instead of difficult. Externalising your images using the Node configuration is really easy and the instructions are on Tiddlywiki.com but I also wrote a tool, which I will post to the group soon that lets you manage external images from inside the single-file app. They behave like regular tiddlers but the payload is external and so doesn't weigh down your file. BTW, 20-50kb per tiddler sounds a bit excessive - you should consider having only the basics inside each record tiddler and then using template tiddlers to add the fancy ui.
