Hello,
I would like to do two things regarding the hover-over text on the thumbnails which say 'Click to enlarge image 'image-file-name''

- I would like the text just to say 'Click to enlarge'. I do not want to display the picture filename in the hover over text.
- I want to change the hover over text for my German and French site, however I cannot see the language files. Please can you tell me the name of our language file and its exact location?

I am running Joomla 2.5.8

-Change the text in the language file : administrator/language/en-GB/en-GB.plg_content_jw_sigpro.ini.
