How to dynamically change image at URL (rename github file?)

If you use render() and return a byte it will work as long as you set the right content type header.

Ok, I guess I also need to figure out where to store the images, and how to pull them into HE so that I can then return them at the endpoint...Any example apps that you know of that do something similar?

Maybe this is what I need?

asynchttpGet get byte data

Ok, I can move forward with doing it that way, thanks!

I tried this but it returns a null response. Not sure what's different here than in the example from that thread.

void getImage() {
    def params = [
        uri: "https://raw.githubusercontent.com/lnjustin/wallpaper/master/cropped%20dreamstime_l_155161055.jpg",
        headers: ["Accept": "image/jpeg"]
	]
	asynchttpGet(sendHttpResponse, params)
}

void sendHttpResponse(response, data) {
    if(response.data != null) {
        log.debug "base 64 data size ${response.data.length()}"
        byte[] imageBytes = response.data.decodeBase64()
        log.debug "bytes size = ${imageBytes.size()}"
        render contentType: "image/jpeg", data: imageBytes, status: 200
    }
    else log.debug "Null response"
}
