I registered and tried "Adobe Photoshop Express" Beta.

Adobe Photoshop Express is a kind of SaaS (Software as a Service/It can be simplified and explained as a web page or web browser based software)

You don't need install any program and files on your computer. You can use it by just opening a web browser and accessing Photoshop Express page from your bookmark.

I know it is still beta version, but it doesn't run smooth yet when I move between tools.
Anyway, its interface is better than other web based photo editor software. Quality is like Photoshop CS3 and other Adobe software.

The most important thing for me is that this will make people who ask me to install Photoshop piratically shut up.
They think all those who know computer and internet so much have a Photoshop installer. And they also think Adobe Softwares are not product they should pay for, these are like kind of Freeware...

Ofcourse, I am a officially registered owner of Adobe CS3.
