Periodically refresh an image with a static URL source on a perspective view

Hi,
I am building a perspective view that uses a static traffic cam URL (.jpg) as a source for a perspective image component. This displays the current image, however the image at the source URL updates about once a minute, so I’d like to automate the refresh of the image. Is there a way to have the page (or just the image component) refresh without user input?
Thanks.

Try adding an unnecessary query parameter to the URL to foil your browser’s cache. Change that parameter every 30 seconds or so to make the image refresh.

Thanks, that helped me get it working… I had a ‘mins’ tag that changes every minute, so I appended that to the URL and query parameter ‘?’ in the expression binding on the source property, and it now updates every minute.
