Any specific reason you are using JPG for these chemistry diagrams instead of PNG? Artificial images with very few colors are RIPE for PNG Indexing (giving you MUCH smaller file sizes).

Because jpegs were sent to me by the client, and because the ePub will be converted to Kindle as well and in the past they handled PNGs badly (sometimes converting backgrounds to black). Perhaps that has changed?
