Linking Picture in excel cell

I am an eye specialist and i am making a spreadsheet which would have the record of the audit that i am doing on my patients. Along with other details i want to give link of the routine followups of their disease picture in their specific spreadsheet cell. I have searched the internet about it where i have come to know about hyperlinking. However, my concern about hyperlinking is that i want the spreadsheet with pictures to be portable to other PCs which wouldn't be possible with hyperlinking. Also including the pictures in the spreadsheet would be very troublesome as the size would enormously increase once the data continues to grow.
I want to include photos in column L, R, V, Z & AD. Can anybody with skills please help me out with this. I am attaching the spreadsheet here.

Note: I have no programming skills
