Sledger,
Thanks for the tip. It works, but it nearly doubles the size of the website.
Each image is placed twice in the "index_html"-directory : once with the original name and once the 'numbered' file generated by XWD.
This is really a pitty : when looking at the html file which is generated by XWD only the orignal named file is used and not the file generated by XWD.
Moreover this does not work for texts (grouped) which are exported as an image.
I also notice that when both jpg en png are used in the website, numbering starts from 0 for each type. Result : two files might have the name 0 or 1, ....
So, its only a partial solution.
Any other suggestions.
