Hi there! I understand you want to delete photos from the Peachy app gallery on your iPhone running iOS 18.6. Just to clarify, are you looking to permanently delete photos from the Peachy app’s internal gallery, or are you wanting to remove photos from your iPhone’s Photos app that were edited or saved through Peachy? This will help me guide you more precisely.

Meanwhile, here’s a general way to delete photos inside Peachy:

1. Open the Peachy app on your iPhone.
2. Go to the gallery or album section where your photos are stored.
3. Tap and hold the photo you want to delete. Usually, a menu pops up with options including “Delete.”
4. Confirm the deletion if prompted.

If the app’s interface is different or doesn’t work this way, let me know what you see on your screen, and I can guide you through it step-by-step.

Also, just so you know, deleting photos directly in Peachy might not remove them from your iPhone’s main Photos app if you've saved them there. If you want, I can walk you through that part too.

Does this match what you’re trying to do? If you’ve already tried some steps, please tell me what you’ve done, so I don’t repeat them.
