Image information for reuse

[jcolomb]

hi all,
I am pulling some images on rdmpromotion.rbiind.io and want to give proper credit, should I include all book authors or only the one who did the images, in the latter case who is it?

In European regulation, I also need to indicate a title for each images. Should I simply name them all "no title" or "Open-Science-Training-Handbook", or are specific titles attached?

thanks for the help!
