broken links for icon-image files

Hi,
I am using the Dream Spa theme and had some old references to these image files that recently stopped working:

custom_icon=”https://wedesignthemes.com/themes/dummy-dreamspa/wp-content/uploads/2014/05/services-ico1.png”
custom_icon=”https://wedesignthemes.com/themes/dummy-dreamspa/wp-content/uploads/2014/05/services-ico2.png”
custom_icon=”https://wedesignthemes.com/themes/dummy-dreamspa/wp-content/uploads/2014/05/services-ico3.png”

Did the links to these files change or do I have to stop using them? What is the proper way to solve this? Thanks!
