Strings within Media Manager are not translatable, help.

Hi Team,

I am trying to translate all language strings for EasyBlog 3.9.xx, however, I found strings within the Media Manager have no effect for my translation. Please advise where I should get the file to translate? I've seen another post mentioning "Customize" button but I found there are more of it.

/language/xx-xx.com_easyblog.ini
COM_EASYBLOG_MM_DELETE_BUTTON="Delete"
COM_EASYBLOG_MM_ADD_IMAGE_CAPTION="Add image caption"
COM_EASYBLOG_MM_ENABLE_IMAGE_ZOOMING="Enable lightbox"
COM_EASYBLOG_MM_ENFORCE_IMAGE_DIMENSION="Enforce image dimension"
COM_EASYBLOG_MM_EDITOR_YOU_ARE_CUSTOMIZING_THIS_ITEM="You are customizing this item"
COM_EASYBLOG_MM_INSERT_GALLERY_BUTTON="Insert as gallery"
COM_EASYBLOG_MM_INSERT_AS_GALLERY="Insert As Gallery"
COM_EASYBLOG_MM_INSERT_BUTTON="Insert"
...actually there are lot more

I guess I am not getting the correct file to translate, please show my some hints and thanks.

Best regards,
Alfred
