Of course. Whether it's a thumbnail or not, you're going to need to
render it somewhat like the page actually is, which means you need to
be able to parse table layouts, CSS positioning, etc etc. It takes a
lot of time to get this working.
I think it might have been Toby who posted here in the past a method of
capturing screenshots of websites using a browser and scripting. I have
utilised this method myself and it works really well. An example of
this is below.
This is on a Linux system. You may or may not be able to do it on other
systems, but it works nicely for me. I run Opera fullscreen on a
1024x768 screen:
system("opera -remote 'openURL($url)'");
sleep(30);
system("import -display :0 -window root temp/$filename.jpg");
The 30 second sleep gives it time to have all the images etc downloaded.
I probably don't need to make it wait that long - just being safe.
