Kagi Translate on iOS can translate text found in an image, but it requires the photo to be taken in the app, or picked via either the file picker or the photo library.
In some contexts (browsing the web, looking at existing photos) it would be faster to have a share sheet item or action for Kagi Translate, which would send the image to the app, and trigger translation by detecting the source language and performing translation to the default output languages.
Take a photo on iPhone
Photo has text I want to see translated
Instead of opening Kagi Translate, clicking the camera icon, then the library icon, from Photos.app I hit the share button and pick Kagi Translate or an action "Translate with Kagi"
Kagi Translate app opens, receives image, performs translation.
This is a pretty standard inter-app operation mechanism for iOS.
