With 680 books loaded on my H20, my .kobo-images folder is 527MB, so tracking about the same as Mingyar. It's worth noting that the Kobo generated a full screen size image for all the books, not just the ones I opened. Since the full screen resolution on the One will be significantly higher, I expect the full screen image sizes are probably at least 10 to 20% larger as well.

The large image that Kobo generated are all 1440 px tall, and range in size from 470KB to 1.1MB

Edit: On further investigation, I see the problem,,, the 'Full' Images kobo generated are all saved with jpeg compression at 100, (according to Gimp scale, when saving with original quality, it defaults to 100, and generates about the same file size.)

This behaviour is probably unique to sideloading Kepub. When Kobo sends the file, do they also send optimized cover images?
