Just discovered, to my dismay, that when I annotate a high-res image or photo saved in a note—whether adding text, or even just cropping it—Evernote reduces its size and resolution to 72 dpi without warning.

These surprises caused me real problems today, and make me worry what other images I thought I'd saved at hi-res in Evernote have had their resolutions reduced below what I need, without my knowledge.
