Notes from Milo 🐨

A phone photo taken upright could land on its page lying on its side — many cameras store the picture sideways plus a little "turn me" tag, and PDF viewers ignore that tag. The page now draws each photo the way the tag says (still the original JPG, not re-encoded). A PNG that was saved with a .jpg name used to stop the whole PDF without a word, and a damaged file turned into a garbage page; now the first just works and the second is named when you add it. You can also drag the cards to reorder them, the reset button says Clear (it said "Add more"), and the PDF is named after your first picture instead of output.pdf.
