Website thumbnails with WebThumb

A quick'n'dirty method to get website thumbnails

Simple Example

First, you'll need to signup for a free account to this service : http://webthumb.bluga.net/register

Then, log into the site into your profile page to get two numbers : your User ID and API key, we'll need them right now.

Create a file called thumbnail.lasso and paste this inside, changing the API key and User ID to yours

!insert lassoscript here
Lasso_ExecutionTimeLimit: 60;
local('url') = client_param('url')!=''? client_param('url') | 'http://www.lassosoft.com';
local('apikey') = 'xxxxxxxxxxxxxxxxxxxxxxxxxx';  //free webthumb API key
local('userid')= 'xxx';
local('size')= client_param('size')!=''?client_param('size')!=''|'medium2';
local('cache')= client_param('cache')!=''?client_param('cache')!=''|'1';

local('service_url') = 'http://webthumb.bluga.net/easythumb.php';
local('datestamp') = date_format((Date_LocalToGMT:date),-Format='%Y%m%d');
local('hash') = string(#datestamp + #url + #apikey);

var('url_params')=array('user'= #userid,
			'url' = #url,
			'size' = #size,
			'cache' = #cache,
			'hash'  = encrypt_MD5(#hash));
			
local('response') = include_url(#service_url, -getparams=$url_params, -timeout=60);


if: string_extract(#response, -startposition='7', -endposition='11') !>> 'JFIF';
	'Error: '#response;	
else;		
	file_serve(#response, -file='example.jpg', -type='image/jpeg',-inline);
/if;

?>

You can now call this page, which will output a LassoSoft site thumbnail JPEG named example.jpg as default values. Modify this to your convenience and you've got your thumbnail system.
