You can subscribe to my RSS feed to get updates about new photos.
An RSS feed provides a brief summary of any new content along with a link to the full version. The feed is delivered as an XML file and it lets you know about any new stuff on the website without you having to check it yourself and without having to hand out your email address to sign up to a newsletter.
Browsers like Firefox and Opera have built-in support for RSS. You should see this icon in the address bar of your browser and you simply click it and follow the instructions to subscribe to the feed. Many other programs such as Thunderbird also have built-in RSS support.
If you're a Linux user then you're smart enough to figure this out for yourself but AmphetaDesk is available on all three platforms.
