The html image element has onerror and onload events that will fire if loading the image fails or succeeds respectively.
With regards to loading an image without knowing the correct URI, the answer is no. Its up to the web server to decide what to serve in response to an HTTP request. If the request is for a resource it doesn’t know about its very unlikely to serve anything other than a 404 error.
