Hi Marcin,

The issue you are observing seems related to the restrictive cross-domain policy of the server, where your pictures are located. I tried binding the HtmlDataProvider to the following HTML:

<html><head></head><body><p>This is a paragraph!</p><img src=\"http://image.freshmail.pl/i/1f62ed907q/qiyczbx36r/patronaty.jpg\" /><br/><img src=\"http://romeo.roy.free.fr/photos/Maroc1/IMG_0930-1600.jpg\" /></body></html>

where I took the source for the first image from your code, and for the second from a site that has a permissive cross-domain policy. As you can see yourseft, if you try it, this results in only the second image showing.

These two articles - here and here, can help you in understanding this issue. Also, you can check this forum thread.

I hope this is helpful!
