This addon is somewhat deprecated as overleaf has implemented this (in a different manner) themselves, theirs does however not fill caption and create a image name. This addon is suitable for quick and dirty uploads where you intend to copy-paste and quickly reference a lot of images in succession, otherwise, just use the new built-in feature in overleaf.
I initially made it for myself as i had the use case where i had to do the arduous task of writing a tutorial in overleaf with a lot of images and autorefs to those images.
Feel free to fork and upload your own as this is a quick and dirty plugin mostly for my own personal use.
