I have an 87 year old female cousin who doesn't use a Cell phone. It's hard to send her pictures of my two new Grandchildren

I thought of a way to take pictures from overseas through Signal and put them on my phone with my other pictures. Then I tried to send them into "notes" on my Iphone then I sent it into Signal on my iphone. Then I tried to Airdrop it to my wife's old Imac that is attached to the printer. Then I realized this Imac doesn't do NOTES at all because it predates notes and has something called "Stickies" instead. So, this didn't work. So, I have to sort of give up for now I guess until I find another way to print these pictures out for her so I can send them on letterhead that we use for a printer that takes photos. Also, these are all digital images so their natural state is not a negative just a digital jpeg image. Technology at some points is beyond anything I want to deal with anymore here at age 76.
