Epub Export: Why deselect Preserving Image Appearance from Layout

The Preserve Appearance from Layout option is at the top of the Images panel of the EPUB Export Options dialog box. AnneMarie, in her Lynda.com title about ID 5.5 to EPub says she doesn't see any reason why someone would want to uncheck that option because then you would just get the image as it is saved on your hard drive.
I thought I'd explain the reason why I, for one, leave the option unchecked sometimes. If my book uses images that are repeated at the top of each chapter or at every scene break within the chapters as is a frequent practice in novels, having this checked will create a seperate image for each instance making the file unnecessarily large. If the feature is unchecked, only one image is produced and all the links are identical.
If anyone knows a better way to deal with this issue, please let me know.

Good catch! I knew about the (bug?) behavior of ID exporting multiple copies of the same graphic, but didn't know that that was the fix. I'll investigate too …
BUT it seems like a huge price to pay for that … to have all your images come in to the epub uncropped and unscaled.
I think there's a script or plugin that will automatically make a copy of all linked graphics, resized/scaled to match what's in InDesign, and then relink. Perhaps running that script before exporting to EPUB with a disabled Preserve Appearance would be the best of both worlds?

I've done quite a few books where these and the art on the title page are the only graphics in the book (mostly novels) so it's no problem there. For books with a lot of illustrations for which I want to preserve formatting, I've kept the option checked and done a grep find/change for all the links after the fact in dreamweaver and delete all but one of the images. It's easy but it is another step and doesn't help toward the goal I'm sure we all have of getting a finished product out of InDesign (though this may never be completely possible).
Another thing I should mention, when I have simple line drawing vector graphics (which these little break graphics usually are) InDesign does a poor job of anti-aliasing the image. I'm better off using Photoshop to generate these graphics. But I like to use vector graphics for the print edition of the book so that's what I have in InDesign. So I just overwrite the InDesign version with the Photoshop one after my epub is generated. It'll be great when SVG is supported. Is that supposed to happen in EPUB 3.0?

I believe SVG is supported in the current version of EPUB, but it's simply not supported in some epub viewers! More importantly, InDesign can't import/export svg.
Well, actually you can with a plug-in: https://creativepro.com/svg…..-epubs.php
I haven't used it in a while; if you try it, let us know how it goes.
I completely agree that ID's conversion of line art is pretty poor. True SVG support in the program would be awesome.

So much for standards!
Unfortunately, if not all readers support svg, I can't use it. But I'll experiment with the plug-in anyway just for laughs and let you know. Thanks for the tip.
And thanks to both of you for all the great podcasts, blogs, training video, seminars, etc. that have helped me with my new venture into professional epubbing! You guys are amazing!

It's worth bearing in mind how easy it is to edit an EPUB so that there are multiple links to a single image instead of repeated copies of the same image, because InDesign gives them such similar names: pic_fmt.png, pic_fmt1.png, pic_fmt2.png, pic_fmt3.png, pic_fmt4.png,…
I know. That's what I meant when I said:
