I won't make screenshots, but the pictures look like on my page
http://derela.republika.pl/colorp1.htm . You can download the pack and preview them with any picture browser recognizing lbm files.
The pictures should be copied into ...\WinSPWW2\Game Data\Pictures folder - it is recommended to create a backup copy of the folder first, if you want to return to black & white photos. Then, you can simply swap folders' names.
I may add there is currently 2540 pictures, minus a couple of alternatives.
