I am a new subscriber to Image Spark a site that allows you to compile and collect images that you've found inspirational on the web. There is a plug-in for Firefox too that makes tagging images pretty easy. I just joined and have only just begun exploring, but I like that I don't need to pull images onto my desktop anymore. I can have my own personal inspiration site filled with images that I use to keep me creative. You can view my current collection here.
