Here is the solution I have proposed via email:

In order to change the icon for the phone number for instance, you will need to add some CSS to the 'CSS overrides' field like so:

for the module:

The images need to be in modules/trombinoscope/images.

for the component:

The images need to be in components/com_trombinoscopeextended/assets/images.

Depending on the extent of the use of the component, you should probably make it more 'general' by adding the CSS to your template and the images in the /images directory of your template.

Fernando,

send me an email, your attachment did not get through.
Thank you!

Hello,

Those icons can be added as explained in this thread. You need to use additional CSS as shown above (example with the telephone).

If you need help with that CSS, send an email to [email protected] with the URL of the page where you need those changes to occur. I will be looking into making this more user friendly in the future for people who want to use icons instead of the font.
