While I love the rich image set readily available to me, I'd like to include custom images (my drawings, photos...) in draw.io documents. Is it possible?
I've tried CTRL+V with a clipboard image but with no success.
You need to go logged into a Google Account to import images. When you are, click the image icon (4th from right on toolbar) and the Google Image Picker appears. Select from the options on the left to either DnD an image into the picker or pick an image from the local filesystem.
