All right, I could have you misunderstood because with my changes all images disappear (mansory and easy slider). I used another way of showing the images but in general I would like to know about that option and how to set it up to work:
When you say: “to load avia.js file from your child theme ” do you mean I have to copy that file with the changed code into the Child Theme Folder? Or should I leave the avia.js file in the parent directory as the child function.php tells it how to deal with the changes? If I do that the images in mansory and easy slider disappear as mentioned. Sorry I am not into php and in which direction the code is working. so I’d very happy if you can help once more please. Thanks alot!

thanks alot, will try this out. It looks like as it is a general code to enqueue the avia.js file from the parent theme. would that mean that I can also do other changes in that script (I actually did) and with your code above I ensure it will be loaded and never overwritten by a theme update? If I have to specify my changes (from avia.js) in the child-function.php, I better take a course on it. but maybe that’s it? anyhow thanks so much for your help and i can really understand when some user write you are a hero. ;)
