How to process CR2 files from Canon 40D with Photoshop CS2

Well, both CS2 and Lightroom 1.0 can not read new CR2 format intorduced by 40D (firmare ver. )
There are 3 options to keep workig with raw workflow:
1) convert CR2 to DNG using Adobe (free) converter DNG 4.3 (note, only 4.3 can do that; 4.2- can not!): http://download.adobe.com/pub/adobe/photoshop/cameraraw/win/4.x/DNG_Camera_Raw_4_3.zip

2) upgrade to CS3/CS4 or Lightroom 1.3/2.0

3) use Canon's DPP tool to convert to TIFF or JPG or whatever. But TIFF or JPG workflow is far of workflow flexibility with raw data (CR2).

Personally, I ended up with upgrading to Lightroom 1.3. It took me some time to adopt to LR workflow, but now I almost do not open Photoshop anymore for the photo editing.

CURL configuratiion on WinXP and XAMPP

In order to configure CURL on Win/XAMPP it is enough to uncomment just one line in php.ini which points to curl dll. It is also recommended to verify the extension path.
There are multiple php.ini with XAMPP1
Run phpinfo() to see which one is loaded. In my case it was "C:\xampp\apache\bin\php.ini" - there the change should be done.

Restart Apache when you have saved the php.ini changes. In some cases you might need to reboot to get Apache running again.
