Photographer problem

After contacting five different photographers that could work one got back about being keen, and she said that she would send the photos to me, but after looking through the ones she sent there was nothing that would work and in the end, she said that there was no way for her to get an older person to model. So I might have to do some drastic measures. This is all a bit too stressful mo I might as well just find some images online as none of the photographers I know at uni does do photos of older people. Why did I do this?

I tried to contact other photographers but none of them had any contacts with older people that would be up to be photographed.

 I even asked my granddad as he does a fair bit of recreational photos of he could take some of my grandma at home but he is not great with technology like that. so I'm a bit lost.

I found this website where you can find images without copyright so that you can use them for anything. I found four images, that would work that I can crop out the parts that do not work. I messaged the photographers and they seem fine with them being used for this brief.
