Imgur Album Downloader

A Pure JS webapp to download entire or parts of Imgur albums.

A modified clone of this: http://dschep.github.io/imgur-album-downloader now hosted here: https://fluffy9.github.io/imgur-album-downloader/

Note: Large albums or albums containing very high resolution photos might not work, depending on how much RAM your system has. You can download whole albums natively on Imgur by appending /zip to the URL.

This is modified to work embedded on your website. It automatically downloads an album when the album id is provided and downloads it to the user's computer. You can embed the link to the album in your website as a hidden iframe. If you want to add a loading bar, the child iframe posts a message to the parent window in the form of "{{ Currently Downloaded Pages }}/{{ Total Pages }}"

Important Notes

• Please replace the imgur client id with your own. They are free and I use nearly all of my quota anyway.
• I didn't add any error checking. If the iframe fails to download something, loading will just stop / not start. To add this you will have to fork the code and add error checking in the controller.js file
• After using this on my website for a couple weeks I got an "uncommon download" warning in the google webmaster console. I believe this is because the zip files generated have random names. Google then started showing my downloads as potentially having malware just because of that 😠. After doing an audit of my website the error went away so I assume they realised the downloads are clean.

How to Use

You will need JQuery and Bootstrap for this tutorial

Change the Client ID

Fork this code and open controller.js. Please change the client id to your own. You will need an imgur account but they are free. You can get one here.

// Use CORS
    $http.defaults.useXDomain = true;
    delete $http.defaults.headers.common['X-Requested-With'];
    $http.get(
        'https://api.imgur.com/3/album/' + $scope.albumid, //i46pk',
        // client ids can't really be secured in javascript.
        // don't be a dick, get your own, they're free.
        { headers: { Authorization: 'Client-ID 9a87b414599044c' } }
    ).success(function (data) {
        $scope.album = data.data;
        $scope.album.images.forEach(function (image) {
            image.selected = true;
        });
        $scope.preserveFileOrder = true;
        $scope.to_download = $scope.album.images;
        $scope.download();
    });

Create the Iframe:

Download button sample html

<a id="download" class="source" style="color: var(--color3)" href="#"><span>[Source 1]</span></a>

iframe javascript

	$( document ).ready(function() {
		
		//When the download button is clicked
		$("#download").click(function(){
			//Hide the download button so the user cannot click it multiple times
			$("#download").hide();
			//Show the download progress bar
			$("#download_bar").show();
			//Create the iframe. Replace {{ imgurid }} with your imgur album id
			var iframe = $("<iframe />",{ src: "https://fluffy9.github.io/imgur-album-downloader/#/{{ imgurid }}", style: "width:100%; display:none"}).appendTo("body");
			iframe.ready(function(){
				
			});
		});
	});

Adding a bootstrap progress bar:

Sample HTML

<div style="padding-top:5px;">
					<div id="download_bar" style="display:none; width:100px" class="progress">
					  <div class="progress-bar" role="progressbar" aria-valuenow="0"
					  aria-valuemin="0" aria-valuemax="100" style="width:0%">
						<span class="sr-only">0% Complete</span>
					  </div>
					</div>
					</div>

Listen to the messages that the iframe is sending and update the progress bar accordingly

window.addEventListener('message',function(e) {
		var key = e.message ? 'message' : 'data';
		// The data as an array. Data[0] is the currently downloaded image. Data[1] is the total number of images to be downloaded. 
		var data = e[key].split("/");
		//Turn this into a percentage
		percent = (data[0]/data[1])*100;
		//Change the percentage of the progress bar
		$($(".progress-bar")[0]).attr("aria-valuenow", percent);
		$($(".progress-bar")[0]).attr("style", "width:" + percent + "px");
		$($(".sr-only")[0]).text(percent);
	},false);
