Unscaled images in responsive HTML, not limited by the AFrame

Hello,

In my unstructured Frame Maker Document I use AFrames to scale the images (mostly screen shots) to the paper size. I use always 150 dpi and the quality is very good in the PDF output (3,200 pages) and in the chm file using WebWorks.

I am now evaluating FM2017 Responsive HTML feature to replace local chm to a hosted Web Help.

Option A:

The responsive HTML may ignore the AFrame size and the scaling and use the 100% best image quality. This makes the images greater but destroys the layout. (Not an issue in my case, because all screenshots uses full left to right in the page)

Option B:

The scale and size uses the original AFrame size. This will keep the orginal layout.

Offering a zoom feature, the user can click on the scaled image to see a popup with the 100% orginal image.

The zoom feature would be nice. But even, if I include the java script part, the images rendered in the ./assets folder are already scaled?

Thanks for your support
