The transition to Photos SUCKS! Why are most of my pics pixelated?

[iMore Question]

Why are most of my pictures pixelated? The info window shows just as much size as the similar pictures from the same "roll" that are clear. Help!

Depending on settings on devices, you may be seeing thumbnails - but you can always retrieve the full resolution photo... I'm still learning how things work...
