Just searched for thumbnail webpage php on google and the first hit provided something usefull (atleast, looks like it). Perhaps worth reading trough that, can't provide you with a direct link tough as I'm a new member
Hi, We have done this with php and gd. I have the code. If you would like to shell out some dollars, i can provide you with that. Contact me in pm, if you would like to.
There is a really simple method: http://open.thumbshots.org/image.pxf?url=SITE URL you can replace google.com with another site url e.g <img src="http://open.thumbshots.org/image.pxf?url=http://www.google.com"> seen this in a few web directories. hope u find it useful
Ah, In case you are thinking about linking the thumbnail from some other location, you can think about a better option at http://www.websnapr.com/ You have the liberty to change the size. But in case you want to create a script all for yourself and keep generating, i can just help you out.
