Hi, I'm working on formatting a short story anthology where there is one image per chapter.

I'm trying to figure out some guidelines for graphics that are valid across platforms (Sony Reader, kindle, stanza, etc).

The OPS doesn't really give much help, except to say what formats are to be supported.

http://www.openebook.org/2007/ops/OP...l#Section2.3.4

I've found this info about covers on ADE
http://blogs.adobe.com/digitaleditio...the_cover.html

I am testing chapters in my browser, and I recognize that what works in a browser may not necessarily work inside a reader.

I am basically coding by hand (or more precisely, making minor adaptations to existing HTML/code which is pretty clean).

Here are some questions:

SCALING IMAGES. how do I plan for image dimensions in relation to the viewing area? Do reading systems automatically scale images? If yes, how do they figure out the optimal image dimensions to use? I want to prevent the image from encompassing 99% of the page (for example)?

IMAGE DIMENSIONS AND COMPRESSION. I took a look at Jelby's excellent Prince and the Pauper epub file https://www.mobileread.com/forums/showthread.php?t=34347, and I see that the cover is 600x800 (136KB) while the other jpegs max at 540x600 (123KB), while a lot of them are under 50K. Aside from the fact that this ebook has a lot of grpahics, are these guidelines good rules of thumbs?

WRAPPING AROUND INLINE GRAPHICS. In the ebooks uploaded, I don't recall seeing any images which are floated into the paragraphs. Is this css selector not supported or workable in reader systems?

If you don't float graphics, then any image will add extra white space. That's what I'm trying to avoid when I use images. What thoughts do you have?

Thanks for your help.
