If you 'right-click' an image file and select "print" from the drop down menu, the photo printing wizard is what comes up
The wizard will print image files which are located on your computer (so in a sense, they are saved). No test unless the txt is part of the picture. I didn't know if you were aware of this or if it's even an option for you, but I thought it would be good to let you know

Oh, eh.. my, well that was simple -- I really just must not have recognized it. But you are right, I didn't need this originally, but at least I got something else out if it; I just wanted to know about picture capacity in documents.

No problem, you can keep the wizard in mind for a rainy day.
I just used it this morning, selected 12 different pics, I selected 2/page and it automatically took it from there.
As for your original question, same answer as before, if your PC cna handle it, the software can too. Just remember to keep saving so if your PC shuts down unexpectedly (power failure, whatever the reason) you won't lose your work.
