Hello Mrs V.
Much better you save the photos in MS Word, then with brief narratives for each photos (description of when, who, where, what occasion, etc for each photos).
Makakasave ka ng space and bulkness kesa sa magpaparint ka ng photos in hard copy, and besides need mo din sulatan at the back of each photo ng description if it is in hard copy. Fyi din po, in case of hard copy photos, they specifically stated that photos must be loose, should not be in binders or albums etc.
Yes screenshots ng communication is fine.
Goodluck
Cheers!
