RequireJS Image Plugin

gistfile1.js

/*
* Example #1 : usage example
*  - Image paths are relative to the HTML file.
*  - Support absolute paths as well.
*  - Appending `!bust` to the end of the file name will avoid caching the image.

require(['image!lol_cat.gif', 'image!http://tinyurl.com/4ge98jz', 'image!dynamic_image.jpg!bust'], function(cat, awesome, dynamic){
	//add loaded images to the document!
	document.body.appendChild(awesome);
	document.body.appendChild(cat);
	document.body.appendChild(dynamic);
});


/*
 * Example #2 : multiple requires for the same file.
 */
require(['image!http://tinyurl.com/4ge98jz'], function(awesome){
	
	document.body.appendChild(awesome); //add loaded image to the document!
	
	//require same image again
	require(['image!http://tinyurl.com/4ge98jz'], function(awesomeToo){
		
		//requireJS will return same image object unless you use `!bust`, 
		//which means it will remove old reference from the document
		//and append it into the new target node.
		document.body.appendChild(awesomeToo); //no visible changes (since image was already in the document)
		
	});
	
	//require same image again
	require(['image!http://tinyurl.com/4ge98jz'], function(awesomeToo){
		
		//requireJS will return same image object unless you use `!bust`, 
		//so we need to "deep-clone" the Element to be able 
		//to insert it multiple times into the same document 
		document.body.appendChild(awesomeToo.cloneNode(true)); //insert a clone of the image

                onLoad(null); //avoid errors on the optimizer since it can't inline image files.

                img.onload = function(evt){

                    delete img.onload; //release memory - suggested by John Hann

        },
        normalize : function (name, normalize) {
            //used normalize to avoid caching references to a "cache busted" request.
            return (name.indexOf(CACHE_BUST_FLAG) < 0)? name : cacheBust(name); 
        }
    });
    
}());

Fixed optimizer integration by changing define to a literal object (see bug report)

Thanks for the tip about config.isBuild and onLoad(null)

moved all my plugins to a new repository: https://github.com/millermedeiros/requirejs-plugins

Hi experts,
does anybody live here? )
can i take image in binary format from it?

thanks in advanse, Andrew.

@xDrgh you would need to convert the image to binary yourself using JavaScript.
