There's a built-in four-gigabyte size limit to the PDB, but I doubt that's going to be a limitation to most books going forward. Probably the constraining factor is the 65,536 maximum number of records (data packets, quasi-files; it seems as though Mobipocket splits biggish files into several of these, possibly for faster indexing) in the PDB.

The format doesn't seem to impose any inherent limit on the size of each record, though.

I realized I now have the Palm MobiPocket Reader on my Nokia 770, and it seems to handle large JPEG images ok - rescaling them to fit the screen. Note that the Palm window is only 320x480 (total screen is 800x480).

I believe that have stylesheets but not CSS. XLS perhaps? (Don't remember the acronym)

Just today I uploaded 2 more books to Amazon, in the original Word DOC format, and they worked fine (based on the previews). Amazon gives you a choice of formats to upload and convert, though I don't know how many formats they can handle.

Since the Mobi software resizes the images why the heck do they not make the books with large images and let the software size as needed? This makes no sense an actually ruins a number of books that need viewable images. May Mobipocket rot for that.

Actually, Mobi files will resize large images down (like, to a PDA). I believe the only real issue there is the increase in file size that you get with big photos, something that older PDAs and other devices were known to choke on.

The more important question is why the heck are Bokeen, Amazon and Irex all using it is their primary ebook format?

Because images are not the primary purpose of novels? Mobi files can be made to have larger images but it takes some effort.

Some books need images to be clearly viewable. if the images are too small, the book is totally ruined. Try telling that to someone who just paid good money for a book that is useless because of old technology.

MobiPocket has taken the approach of fixing the small image problem by switching to JPEG images, but that leaves all the existing e-books with tiny GIF images (and many new ones as well, because publishers are slow to switch - in part because of compatibility concerns). MobiPocket should add a fix for legacy e-books, by scaling up small images. This won't be perfect, but better on large screens than leaving them unscaled.

Part of the problem is that the MobiPocket Java Reader software used by the iLiad and Kindle is the least developed of all MobiPocket's Readers. Other areas where MobiPocket's Java-based Reader is behind the times: can't show large images at their original size, can't set margins, can't change line spacing, can't change fonts (on some devices). The Cybook's reader probably isn't the Java version, and it does have more features. Perhaps Bookeen could take the lead and demonstrate that scaling up small images is a worthwhile thing to do.

The non-eInk versions of the Mobi Reader have an "image mode" which allows you to zoom in on, and (on a PDA) pan around an image. Works very well for things like maps.

The problem is that some of these small images look awful when resized. 8-bit gif images do not always size well. I used Photoshop to size some images pulled from a Mobipocket ebook and they were not good. So yes it can be done. Will you like it? Probably not. The only way to solve the problem is to go back and redo all the books that have images besides the cover. The best solution would be a reworking of the reader so it's up to the standards of todays larger screens.

And the Mobi Reader does have some very nice features which others lack, such as dictionary lookup.

Certainly that is true and I never said it was not. I was just explaining the position, not defending it. Images in novels are not frequent but other books depend heavily on it. Not all ebook formats work well with all genres. Try manga in a traditional reader.
