I recently purchased a iPhone X the pictures that transferred from my iPhone 7 are blurry now. Are all my photos ruined?

Hi there make back up for ur 7 on the cloud then disconnect from WiFi and connect your 7 to Mac or pc then make another backup version that you will choose to set it up manually and pick ENCRYPT DATA then backup to iTunes.

Now all you have to do for your X is to backup first from cloud then back it up again from iTunes.

This is how we do it good luck.
