marcel, you did understand that you will need to edit the template files?
they are in /siteroot/components/com_rsgallery2/templates/microMacro
I think most of this code can be found in the display.class.php file
yeah i understand i need to edit the template, but cant find any settings to change the things i mentioned above. as you can see in the attached screen; i would like to change the way the small popup shows when i hover the thumb...
