[removed] how to force Image() not to use the browser cache?

Question

If I load the nextimg URL manually in the browser, it gives a new picture every time I reload. But this bit of code shows the same image every iteration of draw()

Answer 1

You can't stop it from caching the image altogether within Javascript. But, you can toy with the src/address of the image to force it to cache anew:

[Image].src = 'image.png?' + (new Date()).getTime();

You can probably take any of the Ajax cache solutions and apply it here.
