Hi, I will to know how to write Title and Description in Bulgarian language?

First you have to select from the plugin Default caption (label) handling: Read contents of caption files. Once you do this inside each images folder you will find a labels.txt file. Download it (if you are working remotely) and edit it. Before saving it make sure that it will be saved with UTF-8 encoding.

Thanks, it works :)
Just one note - labels.txt must be saved not only in UTF but also in UNIX format too!!!
When it is saved in Windows format - something works, somthing not :))
