Welp, I made some good progress this evening with discovering how to download photos from my camera to this computer. Enough progress that I'm going to take some pictures tomorrow, and then we shall see! I'm excited about this. I haven't played with my camera for two years because I could not figure this out (it's an oddball operating system on this computer, which is one I bought when I lost my Mac and this was what was available -- long story.)
I needed somebody who could talk me through a few things and somebody just did! So, I'm delighted!
