Images are shrunk in HTML and chm output

[Almtuna]

I did the mistake to ask two question in one (https://community.adobe.com/t5/framemaker/images-are-shrunk-in-html-and-centered/td-p/10882816?page=...), where one of the questions was answered. Here comes the second part one more time:

I have just upgraded my document to FM19.

From the same FM document I am generating pdf, MS HTML Help and Responsive HTML5. The document contains several hundreds of .png images. These images look fine in the pdf output, but the HTML5 and HTML Help output contain shrunk images.

For example one image is 882 x 623 pixels. It has the FrameMaker object properties:
Width 13,744 cm
Height 9,708 cm
Scaling 44,17%
DPI: 163 dpi

The pdf output's image looks perfect, even when zooming in.

However, the HTML5 and HTML Help output contain a shrunk version of the file, which is just 522 x 377 pixels, and is a little bit too blurry.

How can I keep the original 882 x 623 pixels in the HTML5 and HTML Help output?

Before upgrading to FM19, I used Web Works Publisher to create the html and chm output - with original size images.

Go to Publishg Settings, style mappings.

Chose Image Settings.

"Preferred Dimensions", Set both Width and Height to 0pt.

Save and close.

Done!
