We don't provide translations. All language plugins are community driven. If there's an error in the language string you'll need to correct it using a language override or contribute to that language project on transifex. All language overrides are done from the same place as always; the override tab of your language plugin as shown below.

If you need to override Photo then override it from the above page. Not every language string has a set language key. This means the language key is auto generated. The language key can also be just the language string. So for example you could override with the below.
Key: Photo
Text: PHOTO
Note that for the that activity display it will run the language string through UTF8 safe string to lower function as it's supposed to be lowercase as it's in the middle of a sentence.
