Sorry for any inconvenience! Android devices are so varied and there are so many, so we've found many times this could be a device setting.
A couple of thoughts ::
- Did you grant permission to Red Stamp for photos when you downloaded the app? You can alter your settings for all your apps in :: Setttings > Apps + then scroll down your list to find Red Stamp. Give Red Stamp access to Storage and Camera
- Your Photos might have several folders. Please make sure you are checking all your folders.
If you have checked these options and are still having trouble please email us at firstname.lastname@example.org.
