Adobe's giving us all a late Christmas present. You can grab yourself a free, legitimate copy of Photoshop and the rest of the Creative Suite 2, right now, direct from Adobe. No catch.
Well, unless you think having an Adobe account is a catch. Anyway, apparently Adobe's tired of keeping the activation servers running to support legitimate installs of the 10-year-old CS2, so it's decided to just give it away. Sounds great to me.
Handy if all you need is a quick image editor, Photoshop CS2 will still do all the basic things, just not the new fancy smart 'content aware‘ stuff. Free's free, so get over to adobe.com and get downloading.
Update:The install for Mac is actually for Power PC devices, so you'll need Mac OS X v.10.2.8–v.10.3.8 or Rosetta to get it working.
