Online Collage maker

i don't like to install applications on my desktop.. I like uncluttered desktop and like all my files to be in proper folders. Which is why whenever possible, i try online alternatives like Online photo editing, online converter etc.

So i'm glad that somekind soul posted this link somewhere
http://www.collagr.com/Default.aspx

collagr.com is an online collage maker. Of course there's many other sites which offer similar service but what i like most is

- i don't have to register for an account
- I don't have to upload photo's to their site (but there's a down for this)

The down
- you need to already have a flickr or photobucket account.
- currently only can create collagr from those 2 sites (i tried to copy the URL from picasa it doesn't work)

Steps
- http://www.collagr.com/Default.aspx
- cut and paste flickr or photobucket URL
- click Build it!
