CB Image gallery

Is it possible to list all of the users galleries in a masonry layout or is it only possible to show the gallery user by user ? Can non members access the galleries ?

You can display all profile galleries by creating a gallery (menu, module, or field) with an Asset of profile.%. As for the layout it's grid and not masonry. If you need masonry you'll need to implement the template files for that or try restyling the grid using CSS.

Ehmm.. how do I exactly create a gallery (menu item) with an asset ??

Also - is it possible to enable some kind of user comments on the images on the profiles ?

Create a Joomla menu item with a menu type of Community Builder > Plugin. Next select CB Gallery for the Plugin. Then under the Gallery tab set Asset to profile.%.

Also - is it possible to enable some kind of user comments on the images on the profiles 

Install CB Activity and CB Auto Actions. Then in CB Auto Actions > System Actions publish "CB Gallery - Comments" system action.

Thank you. Now I just need to now how to show the comment and not only the name of the person who commented ?

It should already be showing the comment as it does on our demo site. The text looks white as I can faintly see it against the gray background so something on your site is styling the text color to white.
