The HTML parser is the right choice and I assume that the HTML content is extracted correctly, but you don’t know how to change the <img> attributes. There 2 different approaches:

1. By double clicking the <img> tag in the edit field of the Properties window the Tag Attributes dialog is displayed and you can edit all the tags.
   
   
   
   
2. You can switch the mode in which tags are displayed and edited. Open the Options dialog and go to the Tags page and change the option to
   Don't show tags...
   
   
   
   Then the tags will be displayed as follows and you can simply change the text.

Thanks for support. The paths in the tags could now be modified.

Another unlucky behaviour is the target file:

Source / target comparison:

The yellow marked parts are not from the same format. Have I made the wrong settings in my source list?

Is it possible to modify the path to the stylesheet in PASSOLO?

I'm not able to find a line with .css in the text.
