Problem with Maximenu, J1.5, Only use image

Hello! I have a problem with displaying text in the menu.
in the properties of the module i swith on "Only use image" - Yes, so now i have only images, without text. Its good for first-level (top) menu, but not for other. How can i leave images in first-level menu and text for others?
Thanks!

Hi
this option will convert all links without text. For your need you must add the param [img] in each link where you don't want the text and let the text for all other
