A couple of months ago, I upgraded my Flickr account to a pro account. I have had every intention to start uploading all my photos to it but have yet to do it.
I mainly share my photos with the readers on my personal blog, and have been looking for some cool things that you can do with your Flickr account. The fact they provide an API and lots of hacks are available was one reason why I chose Flickr over other photo sharing sites including SmugMug.
I wanted to embed a slideshow into my blog so I did a Google search and found flickrSlidr. It was easy to create and works wonderfully.
Does anybody have any suggestions for other hacks using Flickr? Or are there any arguments on why I should be using another photo sharing site? Flickr lacks a few things that I want but it has close to everything.
