Another Filtering Proxy

[GunGunGun]

Hi whenever, do you think that we can block image based on width and height ? Is there a way to know image w/h without fullly downloaded or maybe we have to download whole image then use window API to detect and then block ?
I know that we can write filter to match width height from HTML Source code, but this way is really limited, there is a lot image that is ad and did'nt have width and height attribute in HTML code, so we cannot have universal solution.

And plus, we also have a list of image resolution that always use for ads.
