I saw one post before about Additional Image's formats but it was long time ago, maybe something changed from that time...
I think it would be convenient to be able to attach TIFF images for multipaged documents for Sources.
So, I have to create source and Either to make A SOURCE for each page of multipaged document to indicate that this is exact place of this source that confirms the statement or to create ONE BIG source to which are attached all the pages of this document and indicate somewhere which page confirms the statement (taking to the account that if I use this Big source I have each time to do something because ONE SOURCE contains only one possibility to indicate which page of the multipaged document contains the confirmation).
Maybe somebody have already decided how to handle the problem more efficiently. My request for the TIFF file doesn't solve the problem it just simplifies of handling pictures in the folder where they are saved.
Thanks for your attention.
