You're probably looking specifically for MediaWiki:Oasis-upload-photos-title which for most wikis will be: Upload a Photo to the Wiki

Some others (not sure where these are all used):
 * MediaWiki:Oasis-add-photo for most wikis will be: Add a Photo
 * MediaWiki:Oasis-add-photo-to-wiki for most wikis will be: Add a photo to this wiki
 * MediaWiki:WikiaPhotoGallery-upload-info-upload for most wikis will be:  Either upload a photo from your computer 
 * MediaWiki:Wmu-upload-image for most wikis will be: Upload Photo

If you can't edit the page you want to change as an admin, see my earlier message about unlocking.
