GramE - you sound like you have been having one of those kinds of days with that bobbin escapade. Sounds funny now but I know how frustrating it was while in the midst of it. And don't get me started on new technology! Even when reading through all the brochures and owners manuals (if there is an owners manual that comes with the gadget) I still can't figure things out. I had to get a new phone and I still can't figure out how to turn on the flashlight feature! Time to search online for instructions....
I can't help you with the picture issue. I take pictures with a point and shoot or use the pictures that are connected to my phone on the computer. I resize using microsoft paint.
I hope today goes smoother for you!
