Screenshots of website

NeedHelp · #1 (**permalink**) 08-01-2006, 06:25 PM

How can I take screenshots of a website and display it? I see a lot of companies doing this now and they seem to be using PHP.

How can I do this?

so you want to like enter a url in a form and then use php to generate an image of the web site?

if so im looking forward to hearing some feedback, i will also need something like this in the future

In PHP, this is not possible.

There is a non-programming way to do this. Press PrintScreen on your keyboard, open up Paint or Photoshop, press Paste (right click > Paste, Edit > Paste, Cntrl + V, there are many ways to do it), size it to your link, save it, and then you can upload it to your site or wherever. Hope I helped.

Not sure how it works, and although it is for windows, it may be worth looking at.

Here's the link to the app

http://bluga.net/webthumb/

You could easily write a script to send url and receive back the image. I believe he also has instructions on how he set it up.

I havnt read everything, but i guess the php would execute a C++ program on the server or something, i dunno, but it cannot be totally done using ONLY php.

I find it much easier with the printscreen button :-)

**TcM** · #7 (**permalink**) 08-30-2006, 05:34 PM

Yeah lol just Print Screen! rotfl why using all that code?

***John*** · #8 (**permalink**) 08-31-2006, 04:47 PM

well why create a program for anything when you can do it manually?

it all depends on the time required to do the task manually. Sure if he wanted to only take 10 screenshots and display them, it wouldnt be worth the few hours it may take to create the program, but perhaps if he wants to make a web crawler to take a screenshot of every website and make a thumbnail in the same process i think it would be much better to create the program...
