FB2 supports illustrations (jpg, png). As for CSS, fonts, and other such embeddings - they are anti-features from a reader's perspective. Why instead of adaptable, and user-tunable semantic markup would I prefer some guy's tastes, or some company's corporate style pushed on me? Besides, there's a big surface for bugs in epub. It happened to me to buy an ebook which froze my reader until I weeded out CSS, and fonts from it with Calibre. Ironically, it also, made it easier to read.
