It's a program you have to download. You can't use Photoshop on a site. Get the trial at www.Adobe.com
You buy it on their site, then you're able to download it. Get the 30day trial from www.adobe.com first to make sure you like it though.
you should check the requirement before you download Adobe , after use a few day, you can buy it, otherwise after 30 day you must buy it or else...
you can download a trail of 30 days on the adobe site, but when it expires u have to buy it, u can do that via the site, than they give you a number you have to type when it starts up ( once ) i didnt know what it does when u redownload it after ur trail expires, but i think u would still need the activate number but to buy it, its so expensive, i would never buy, but i do have ps cs2, thanks to my dad, he works with pc every day and its his job, and he knows how to get it without having to pay for it :lol: :lol:
Get a copy of the regular CS somewhere, It's just like flash, you can get it very cheap once there is a new version, but the newer version has no ground-breaking improvements what so ever exept for just MORE filters.
