> [@\[valid reason\] Loading image outside Preload (p5js)](https://discourse.processing.org/t/valid-reason-loading-image-outside-preload-p5js/32234):

> Hello! I want to know if there was a way to make sure an image was loaded when loading it outside Preload. I sometimes get “Uncaught ReferenceError: loadImage is not defined” and sometimes it loads. It doesnt seem to be predictable. The reason why I need to load outside preload is because I am creating a “preview art on your wall” module where clients load pictures of their wall at runtime in a product page via a “upload image” button in the page. They can change their wall as they please.
