As I had hoped, the image slideshow function in the conversation nodes, despite saying "TGA to display" don't have to be Targas. Targas are large files.
When I reskin cloned models, I tend to save the TGAs I use during testing using RLE compression. When I'm satisified with the new textures, I convert them to DDS and compare the file sizes, keeping whichever is the smallest.
An RLE compressed TGA file can be a lot smaller than a DDS if there are large areas of solid colour (such as in tint or glow maps). For complex images, DDS usually proves to have the better compression.
The problem with JPGs is that too much compression introduces visual artefacts, especially if there are large areas of solid colour (like text on a black background). You don't notice them quite so much in more complex images though. An RLE compressed TAG that is mostly black will often be even smaller than a JPG, with no compression artefacts.
