I really only need an image of what one would see in web browser if one point to that URL. I do not care it to be interactive. I also don't want to get the content ("mirror") of stuff that URL points to on variety of "depths" - I don't want to use wget or curl for this reason. That is what I tried first and it breaks with at lest one of the web sites - they do seem protect themselves from "robots" or similar. And we don't need it. We just need to show what they page shows today, that's all.
