I don't recognise the project "content.foto..." and so I don't know how or where the project is translated. If it's something to do with translatewiki.net, then you will have to give me more information before I am able to help.
Go to the page that you are trying to translate. Then go to the address bar and type ?uselang=qqx at the end of the URL address. Press go. See example. The names of the messages should appear. You should then be able to put the message title in the translatewiki.net search box and find it that way. If that doesn't work, please ask again.
I apologize. show photos in English I need to translate this word into the Chechen language but can not find here Posts.
To find this group in the translation tool is quite longwinded. You have to expand MediaWiki/MediaWiki extensions/Extensions used by Wikimedia/Extensions used by MediaWiki - Main to find it. All the Wikidata messages are in groups called "Wikibase...", just to add to the confusion.
All the best.
