Web Page Screenshot

[mareeus@gmail.com]

Hi,

Are there any ways I could get a screenshot of a web-page at a
specific address in jpeg via php script?

Regards,
Marius.

Not unless you find an extension that is able to output an image based
on the requested page internally or write a script that builds an image
using gd or ImagaMagick features based on the html output.

Yes this is what I'm hoping to find, but for the moment I haven't
found such an extension.

I think that if you use KDE desktop, then Lynx can output image files.
I'm sure I've done it on on of my Linux boxes here.

If you have a dedicated server, then yes, this is possible. If not, then
the chances are you don't have the correct permissions set up to do so.

The basic technique (on a Linux server) would be to constantly run a second
X server instance as ":1", and have a browser, such as Mozilla or Opera
running full-screen on that display.

When you need a screenshot of a site, you just use PHP's system() function
to run the command which tells your browser to go to the correct web page.
Then have your PHP script wait for 10 seconds to give the browser time to
load the page up, then run ImageMagick's "import" command to take a screen
shot of display :1.

Be aware though that this can be used by evil crackers as a proxy. Say for
example, you have a script which takes screen shots of websites like this:

http://yoursite.example.com/shot.php?shot=http://example.net/

And say I'm trying to crack into example.net's site through an SQL
injection vulnerability. To exploit the vulnerability, I'd normally just
request the following web page:

http://example.net/search.php?q='; DELETE+FROM+use rs;

However, if example.net are smart, and have noticed me poking around their
web server trying to find a vulnerability, so they've blocked my IP
address. So what do I do?

http://yoursite.exampl e.com/shot.php?shot=h ttp://example.net/search.php?q='; DELETE+FROM+use rs;

And now, as far as example.net are concerned, it was *you* who hacked
their site.

So if you decide to implement such a feature, beware this security
problem. There is no "easy fix" for it, but I'd suggest things like:
respect robots.txt, disallow requests for screenshots of URLs that contain
a question mark, and log all requests (even log requests which you've
disallowed).

Depends on the OS and webbrowser you want to use for making the
screenshot... On windows you could use http://iecap.sourceforge.net to
make 'IE-like' captures...

If the end result is to be shrunk and used as a thumbnail for a links
page for example - then that would probably be quite acceptable and a
reasonable way of doing it .

Yes, i need this for small thumbnails related to some web pages. I
prefer a simpler solution and hope to avoid running firefox or ie on a
server and take screenshots of the screen. I need a small script to
generate a that small image of a web page to associate it with my link
in the database. Hope it can be done simpler.

How easy or hard depends on how much or how little you know about php .

Most of the regulars on here could probably write a basic script to do
the job in less than 2 hours as they would no doubt have lots of the
code already written and as such would only really need to tinker around
with it in order to get it to work .

Would write it myself if i didnt have more important things to do and as
most seasoned users on here dont write code for other people - i'd say
your up shit creek matey .

I'm not asking for anyone on this forum to write my code. I hope to
find someone explain me a little about ImagaMagick or Gd and help me
understand better what i have to do. I have never worked with
ImagaMagick. Telling me that the code can be written in 2 hours won't
help me too much because as you can guess i wouldn't have posted any
question here if i could write the script.

But the real reason i have posted here is that i thought there might
be some code already written for this thing and avoid reinventing the
wheel.

So if you really want to help with some links to code already written/
tutorials ... would be just great.

Look at it as a logical step by step process .

(1) create a 800x600 blank image using gd or im

(2) grab the html code from the website

(3) write script to scan html code for stuff like background colour

(4) fill 800x600 with found background colour (or white if none found)

(5) write script to check for <imgetc in the html code

(6) paste images onto 800x600 image

(7) write text onto 800x600 image

(8) shrink 800x600 image to thumbnail size

Even if you cant actually do it - you will learn loads from trying .

The mind boggles! Do you really think you can write a full-blown
standards-compliant HTML+CSS renderer in 2 hours?! If so, a well-paid
job at the Mozilla Foundation is calling for you!

The only practical method is to spawn an instance of an existing HTML
rendering system (in most cases, this is a full browser -- e.g. Mozilla,
Opera) and take a screenshot (using ImageMagick if you wish).

Take a deep breath and calm down toby .

(8) shrink 800x600 image to thumbnail size

But then you snipped that part from your reply didnt you :-)

And what difference do you think that makes? My point is that no-one can
write a decent HTML+CSS rendering engine in two months, let alone two
hours.

In your opinion - what are the problems ? .
