@derOJ hm…
let’s open the developers window, ctrl-shift-i,
and select the console tab
put a unique part of the name of your module in the filter field. it will show only messages from your module.
and select the elements tab
click the upper left point of the element tab
and navigate it over your image element.
the css tree for your module content will be displayed.
typically for a module, we use a div as the container for all the module content, and return that from the getDom() routine. mm the inserts that div element tree in the correct ‘position’
what is the url specified in your modules config.js section?
