Aviary.com is a site that allows you to capture any webpage from any browser by simply putting Aviary.com/ in front of the URL!
So to capture our home page, go
http://aviary.com/www.australianwebmaster.com.
Once captured you can make some alterations if necessary and then save to your desktop, or publish online.
Their online image editing tools (which includes a vector editor) can be used separately and are aimed to avoid the need to purchase Adobe Photoshop.
Oh, and these tools are free.
