I have been very happy so far with "Responsive Custom Menu", however it does not have the option to pull in thumbnail images for categories and subcategories on the menu. I was about to extend it by adding a
getThumbnail call to the getter and renderers for this navbar, but ran into some issues where it did not construct the url properly.
It seems that the main files to modify would be
app/code/local/WP/CustomMenu/Block/Navigation.php and perhaps
Can anyone provide some specific modifications that would insert the thumbnails into the menu for further styling?
Additionally, I'm fine with modifying this extension directly to provide these thumbnails, but would there be a better method to extend an extension such as this so that updates are still tenable and likely still work?
It seems that this may hold some keys here to implementing this properly: http://www.h-o.nl/blog/using_category_images_in_your_magento_navigation/
