Online image editting

Recently, I had to do some image editing for my friend's blog. I did not have Gimp installed on my Arch system and Gwenview can do some cropping but not much else. Some time ago, I was thinking of having a site that allows editing of images online. It was just a random thought and I did not have the knowledge to implement such a site. However, now that there was a need for such a site [because I did not want to install image editing tools as do it very rarely], I googled for it and found this nice site to help me out. It had a Photoshop-like UI and worked nicely for my needs. I was glad to get my work done [and to know that my idea was feasible].
