Me and my team love to make flow charts in Miro with app wireframes and my earliest designs. However the board is evolving quickly - people draw lines and connect images…
So with the current state, not even that you have to re-upload every new version of every single image in your board. You also have to separate every image from all it’s connections - to be able to replace it in the first place!
Something like, right-click, “Reupload image” would help just a little - the best way would be to chose from a list of embedded files or even folders that get updated automatically or manually.
