Error in Gavick Photoslide GK3

I have found the error(Gavick Photoslide GK3(2)) and How I can change to my lang(1)?
I've marked the spot for my attachment(1)(2).

Joomla 1.5 myStore quickstart + vm 2

All translations you will find in template language file so please look at root/languages/en-GB/en-GB.tpl_gk_mystore.ini. The tool tips are auto generated by browser are without modifying code of module you can change this behaviour but this change is beyond our support. Please also set proper title for topic because I don't see any error from your description.

Thanks so much for all your help.
