You don't want the browser to download it everytime, but instead to ask
the server if the image was changed. Of course this requires proper HTTP
headers to control the caching. For static images the server usually
does this already (Apache servers for example send Last-Modified and
ETag headers), but it also depends on the browser to respect them.
