Now that we are all hopefully on the same page, the main problem we are facing when thinking about making this more intuitive or flexible, and what we’ve been discussing above, is that the ideal units of measurement are unreliable or difficult to extract from any form of WYSIWYG mechanism rooted in a print-based context, and particularly so in a program like Scrivener, where layout is something done to source material, rather than being an inherent property of that material (like in Word).

For me, it has been an agnostic writing studio that has handed over granular print/layout work to post-compile WYSIWYG tools: of its twenty compile formats, only print and PDF are end-point compiles. Need to reset my brain.
I don’t really get how that squares with Amazon’s 300 DPI requirement: if I tweak an image in Preview, it asks for a resolution, so doesn’t that figure need to be 300 DPI for Amazon? The dumbness of that question will undoubtably seem immense to those of you who are lucky enough to see both the wood and the trees.
And, to me, it still seems as though the image placeholder tag is the simplest way forward, (1) because it allows users to switch different images/resolutions in and out of final compiles, and (2) it allows users to use the ebook=xx% setting (which isn’t possible with an image imported into Scrivener?).

If the image exceeds 800x600 in either direction, then it assumes the best mode for displaying this image will be relatively. All size information will be replaced with “width:100%” as an inline CSS style.

AmberV: what about vh and vw units — these are relative to viewport width and height, easier to conceptualise than width+height (which is relative to the containing block)? What I don’t know is which, if any, ereaders support vh and vx?

Why, out of curiosity, 800x600 in particular?

It is very likely that whatever you are referring to (Sigil, etc.) are not treating images for the print metadata in the least. They are discarding that information, so all they see is your 1080x image and they treat it as Scrivener would if you used 72 DPI with it.

Can’t Scrivener do the same? Discard the print metadata or assume 72 DPI instead of the image’s existing DPI? Wouldn’t that solve the problem?
