I don't have Windows 8, but I did some searching, and apparently there's a new "Fresh Paint" application that may be the drawing program you refer to. You can still get to MS Paint, though; here's a short YouTube tutorial:http://www.youtube.com/watch?...
If you can't view the video, it suggests simply typing "paint", which should bring up an application icon. Or, right-click on a blank space on the main screen, click on "all apps", scroll to the end, and look for the "paint" icon.
However, if all you want to do with your photos is rotate them, the Windows Photo Viewer should do it very easily. If it isn't the default viewer for photos, here's a page describing how to make it the default:http://www.tomshardware.com/---/switch-default-image-viewer-windows.html
Or you could right-click over the image and select the viewer from the options listed there. I've found the photo viewer handy for the rotation issues, as I can click on the "rotate" icon for each picture and then skip to the next image right away; at least on my computer, the changes are saved by default.
Hope that helps!
