Firts of all, Thank you for the fast reply and support.
I explain a little what i do.
On joomla, as you know, is possible to ovveride also the php file in template.
I want to do this because if you update the component i don't lose the modify (i want to change the filter bar of the component).
So i create under HTML folder of template , the folder com_zhgooglemap and then into this the folder palcemarks. I put on this default.php thant i take from the component folder and i work on it.
I only copy this file, without change, and the icon are right!
:woohoo:
