Hello Corriganville,
Welcome to Apple Support Communities. It looks like the photos on your iPad are smaller in size, and we'd be happy to look into this with you.
Do you recall anything changing on your iPad before noticing this issue? Like a software update, or installing an app?
Are you having this issue with photos only or with photos, and text being smaller than before?
Have you tried to restart your iPad? If not, please give it a shot, and let us know if that helps:
Restart your iPad
