Hello I want to know for example script for image hosting which is better optimized and that image is indexed in google will count more revenue for one click, or is the same revenue click if user click on ad if image is shared on some other website?
Images hosted on your site makes sense, and you will get ranked for those images given you put proper title, alt text and description for each image and give them their own dedicated page. It comes down to hosting and how much space you have for your images. You might need to jump to a VPS if your site is heavy, or worst case, a DS.
