Good afternoon formulaone128,
Welcome to the Apple Support Communities!
It sounds like like you are not able to open attachments in your Gmail account. Were you using the Gmail app, or the native Mail app for iOS?
Do you have any other email accounts with photos attached that you can check?
You may need to go to the Gmail webmail page and sign in to see the missing emails and attachments.
Then delete the Gmail account and re-add it if using the Mail app.
- Open the Settings app and tap Mail
- Tap Accounts
- Select the email account you want to delete (in this case Gmail).
- Tap Delete Account at the bottom of the screen.
- Tap Delete from My iPhone again to confirm.
Add an email account to your iPhone, iPad, or iPod touch
If the issue persists, please reply to this thread and we'll do our best to help you!
Take care.
