thumbnail size

Assuming your thumbnail size is set to 150 x 150 on the settings -> media page, you can do it like this to make them 150 x 150 in the store locator.

Add this code to the CSS file in your active theme folder.

#wpsl-stores .wpsl-store-thumb {
    float:right;
    border-radius:3px;
    margin:7px 0 0 10px;
    width:150px !important;
    height:150px !important;
    padding:0;
    border:none;
}

thanks for your kindness.
Another question can I somehow make the map zoom does not work when you slide the mouse over?

It would be of great help to me.

You mean to disable the scroll wheel zooming.

You can do this on the settings page by making sure the “Enable scrollwheel zooming?” is not checked.

Hello, thank you very much for your help, you have a buyer when available the PRO version.
Effectively I mean that my website but I do not see that option settings.

a greeting.

Hello, I upgraded to the new version and now I can not put thumbnails in size 150 x 150 px as he had before. Is there any way?

In the section of the plugin tag does not save my tags in my language (Spanish)

You will either have to make the CSS code more specific, place the id from the parent div before the code I provided. Or add the code example from the “Usage” section to your functions.php, and change it to 150.

Did you enable tag support yourself for the store locations, they are not visible by default. Or do you mean categories?
