Photos in browser don't update

[sitestreet]

This will be the browser cache doing it. The trick is to add something to the end of the URL so the browser thinks it's a different image. Something like ?1929483349 where the number is either random or maybe the current timestamp. So you'd have the URL looking like this:

image.jpg?112493275898

Update image in modal, won't update

I have an image in a modal and the src comes from a text-input. When I update the image using another modal which saves the image as the same file name as the first one, it will not update the image in the original modal. However if I delete the g out of the .jpg in the text input and then retype it will update the image. Is there a way to get this to do it automatically. ? I have tried added model update, but this does nothing.
