The Free Website Project

Taking and resizing screenshots can suck up a lot of time. These services will capture any thumbnail for you, and serve them up as an image that you can hotlink into your own pages, forum posts, or articles. I have included only those that work reliably and are easy to use here, along with a summary of the size of thumbnails, the code used to embed them, and my general impressions of the service. There is a thumbnail next to each service, so if it is not showing up, that service is not functioning properly.

In addition, you will notice that there are bookmarklet links for many of the services, which you can drag to your browser’s toolbar for quick snapping. Simply open up a webpage, click the bookmark, and you have yourself a thumbnail of that page from your service of choice. Credit for this idea goes to TechLifeBlogged for the first Websnapr bookmarklet, I simply modified the code to work with the other systems.

ShrinkTheWeb
	ShrinkTheWeb is simple and reliable, with good speed and uptime. It requires a quick registration to use, and offers both HTML and JavaScript APIs to get you started. The most unique feature this service offers is a PHP script which allows caching of your thumbnails on your own server, speeding things up and acting as a good safeguard should the main system ever go down. Unfortunately, bookmarklets cannot be created due to the way ShrinkTheWeb displays images, but the service does work, as you can see on the left.

SnapCasa
	SnapCasa is a popular thumbnail service, and one that I have used in several of my blog posts. The nicest feature of SnapCasa is that it loads images quickly when you request them, rather than giving a “thumbnail queued” notice. Registration is required, but it’s very quick and painless. One unusual feature of SnapCasa is that the thumbnails are a little on the small side, the largest size being 280x210. This can be an advantage, especially because the images are not obscured by an attribution watermark like the one used by Websnapr.

iWebtool
	iWebtool has been around for a while, and offers a simple rollover preview option in addition to their thumbnails. Both options are very easy to implement, and there is no registration required at all. The only drawbacks are that there is only one size available, and the service does not seem to support certain types of media like flash. Also, the shots tend to have a strange looking border around them.

Picoshot
	Picoshot is about the simplest thumbnail provider you could possibly ask for. There is no registration required, and you can start using it almost instantly without much trouble. There are 2 ways to encode the URL you want to capture, but the only difference is whether you include the http://. I would not recommend Picoshot, however, because it is too simple. There is only one size available, and thumbnails take quite a while to load. Perhaps most importantly, though, is the fact that they only support taking shots of the front page of a domain, which rules out several potential uses.

thumbalizr
	Thumbalizr looks fairly new, and the features are a mixed bag. On the positive side, there is no registration, the API is simple, and it takes far bigger shots than any other service. They’ve served 500,000 thumbnails, so you’d think the site would be working by now, but unfortunately there are parts that don’t behave like they should. These do not, thankfully, affect the thumbnails. My main complaints with the service itself would be the speed of capture (very slow), and the box that says “by thumbalizr.com". That box is distinctly uglier than any other that I have seen, and, although I understand the temptation to have attribution, it is better off removed.
Sizes: Any width <1024

Websnapr
	Websnapr is always a reliable choice, and it has a very nicely done preview bubble option that you can install on your website. There is a nice selection of sizes, and I have never know it to go down. There is a registration required for the developer key, which takes almost no time at all. On the downside, there is a little attribution text in each image. It is not as ugly as thumbalizr, though, but can ruin the look of small images. Also, Websnapr shows an ad when your thumbnail is still queued, which doesn’t add much to the look and feel of your site. For more information about websnapr, you can read my in-depth post about it.
