1. I would just like to know how i change the text where it says " This tab contains a basic no-frills image Gallery for CB profiles ".
This is defined in the plugin language file. You can change it there or (if you dont care about dual language sites) you can just change it in the tab definition.
2. I am not sure how to change the tab text. At the moment it says " CB Profile Gallery ".
Same answer.
. Where abouts do I set the amout of files allowed and the amount of space they are allowed to use.
Default settings are set in the tab parameters. You can over-ride for individual users in their profile (CB user management).
These are not detailed answers but should give a newbie enough info to start him/her looking.
Ok.. sorry to ask, but I've been searching for the plugin language file and can't find it. Could you provide a default path? I looked here and don't find that text: components/com_comprofiler/plugin/language/default_language/ default_language.php
Thanks!
