Google Chrome's application shortcuts turn any website into a separate item on your Windows 7 taskbar, but unfortunately many sites have low-res icons that make your taskbar ugly. Here's the simple trick to make your taskbar beautiful again.
Once you've pinned a shortcut to your taskbar, you can still modify the shortcut properties by right-clicking on the taskbar button, and then right-clicking again on the name of the shortcut. From there, you can access the real Properties menu for the shortcut. Of course, if you haven't pinned the shortcut to your taskbar, you can access the same Properties menu from the shortcut in the Start Menu.
Click the Change Icon button, and then browse to find a new high quality icon on your system — this can be one of the built-in Windows icons, but for best results you can find a better icon on a site like IconFinder. Make sure to grab the highest quality one you can find, download it as an .ICO file, and save that file in a safe location on your system — I put mine into my Dropbox folder.
Once you're done, you might notice that it sometimes takes a minute for the change to take effect, but sometimes closing and re-opening the application helps speed the process along.
I've personally used this technique to use different icons for different sessions to the same website, or just to improve the quality of the icon, like the Remember the Milk icon shown in the screenshot above, which you can download from here.
