And the mirror revealed a face she didn't know
Today was mostly a loss in terms of sleep and staring at the screen, but later in the evening I watched an unintended double feature of The Prisoner of Zenda (1937) and Outrageous! (1977) and that was a great improvement. I may attempt to talk intelligently about one of these movies at some point, but not tonight.*

I'm actually surprised your computer doesn't have any image editing software. Windows has come with a version of Paint since forever, though I don't remember how good it was for resizing images. Mac users usually brag about how their computers are made with artists in mind, so I assume the mac would at least come with a default analogous programme. I advise you to poke around (assuming my Paint Shop Pro doesn't work).
