Pictures on my ipad air 2

First, you’ll need to ensure that your iPad is updated to iPadOS.

Next, you will require an Apple Lightning to USB3 Camera Adapter - model A1619 - to connect your external storage device. This specific Lightning Adapter incorporates both a USB3 Type-A connector and an additional Lightning port to power both the iPad and connected storage device. Additionally, you’ll need your Apple charger, ideally rated at 12W or more (you may already have this).

Once everything is connect, open your Apple Photos App. Find the pictures that you wish to copy to your Memory Stick, tap Select at top-right of the screen - and tap on each picture that you want to copy (a blue tick will appear on each selected thumbnail). Now, tap on the Share icon at top-left.

From the Share menu, scroll down and tap Save to Files. Find your Memory Stick in the locations list, tap, and then select Save. Your selected photos will now be copied to your Memory Stick. Done 🙂.

I hope this comprehensively answers your question.

Just as a Note, make sure the stick is correctly formatted. The iPad is a bit limited in formats it supports for memory sticks and external drives. iPadOS does not support reading or writing to Windows NTFS formatted drives.
