"Photo-sharing web application Flickr is like an onion: it has many, many layers to discover. Last February I published an article here on Lifehacker called Tips for Flickr beginners, a quick rundown on how to get started on Flickr. One year later I’m still as big a Flickr fan and user as ever, so it’s about time to point out some of the more advanced features of the amazing, ever-evolving (yet e-less) service. If you’re not already a Flickr member, do head back to the newbie article and get yourself going. If you’ve already got yourself a Yahoo! account you’re halfway there. Existing Flickr users, follow me. Today we’ll go over some of the more advanced but useful features you may not know about in Flickrville."Some very cool tips like emailing pictures directly to Flickr. Basically, most of the instructions relate to those who want a photo blog. Tips include how you can associate a blog with photos that are sitting on Flickr. Cool stuff, I really think that Flickr is doing things well and I am happy to see that Yahoo has not crippled the product after having acquired it.
