How can get the pictures from my iPod to my iPad without a computer?

Email or icloud.

Or use a WiFi photo transfer app.

WiFi Photo Transfer Apps for iPad

Then there is absolutely no way to get the pictures from the iPod to the iPad unless you import them to your computer and then import them inor iTunes and sync them to the iPad.

Where did the pictures come from? Which iPod version do you have?

I wasn't trying pry asking about the photos, I just couldn't think of how you got them on the iPod without syncing them in the first place which is obviously what you did. I'm sorry but there is no way to connect the two devices together to ransfer the photos. You will have to use a computer.

I'm sorry, that there isn't another way.
