I am trying to translate for pt_BR messages appearing in the picture.
1 - Edit the file jwsigpro.php
2 - Translate the message (line 82) "Navigation tip: Hover mouse on top of the ..."
3 - Translate the message (line 84) "You are browsing images from the article:"

Saved, updated my page in my site. But when i open the pictures, messages still appear in english.
Realized that the same messages also appear in the file "jwsigpro.xml. Also translate the same messages in this file, but still showing in english.
Interesting is if i comment the lines 82 and 84 in jwsigpro.php, messages do not appear. This indicates that this file is really responsible for the messages.

I ask because it is translated?

ps: sorry for my english

I have the same problem.

Somebody have the solution ?

ps : sorry too for my english... ;)
