Thanks for providing more information. Please note that you should not cause permanent additional load just to save time when updating the HMI every now and then. There might be other ways to somewhat automate this so that the HMI has the correct information without having so many item subscriptions (which is not an issue for WebIQ, but will put more load on the hardware). I still haven't understood exactly what you're trying to do there because I assume you have many images on different parts of the HMI, but not all might be visible at any time probably which means the code would have to be adapted/duplicated etc. You should familiarize yourself how WebIQ uses JavaScript for its functionality, e.g. by looking at the Scripting Demo in detail. Otherwise you'll have to ask a lot of questions to get your code working and prevent issues. Please see the documentation for the subscribe method specifically. You also need to understand that you have to unsubcribe when your LocalScript is unloaded, e.g. when used inside a screen view. Otherwise your code will cause memory leaks which might crash the browser in hours, days, weeks or months.
