prestashop - custom image size defined by theme

Question

It is any option/code to define/change image sizes by theme so it will be in the list in back-office when the theme is applied?

I'm creating new theme for which i need to add/modify some image sizes and will be much easier if that can be defined inside the theme instead of manually defining that in back-office every-time the theme is applied.

I've spent some time googling but no luck ;-(

There's config.xml file that the "themeinstallator" module is using, when installing a theme.

Let's say that you have zip file of your theme with the following filesystem:

/modules/*.*
/themes/yourtheme/*.*
/config.xml

In the main folder you must have config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<theme version="1.0" name="yourtheme" directory="yourtheme">
  <images>
    <image name="small_default" width="71" height="71" products="true" categories="true" manufacturers="true" suppliers="true" scenes="false"/>
    ....
  </images>
</theme>

The attributes and values correspond to the ones from the BackOffice > Preferences -> Images page.

The easiest way to do that is just to export the theme via the "themeinstallator".
