Hi all,
Maybe this already exists in org, but I needed a function that looks at
all the image links, signals if the link is broken or not, copies the
files into a folder and relinks it.
Comments and crits are greatly appreciated, I started coding elisp 2
weeks ago, so any and all pointers and tips are welcome.
