I want to change my Pictures Folder icon to being black and blue like the logos surrounding it. It’s not even clear looking at this which one it is. Currently it’s the top one shown here and showing the contents of the folder. I’m going to both change the icon, and change this setting so that it shows the icon, and not the contents.

The first thing I need to do is select the new file that contains the new logo. Instead of opening it, though, I go to the FIle Menu and pull up “Get Info,” or press Command-I.

From the resulting pop-up, select the tiny icon in the upper left corner and go to the Edit menu and pull up on “Copy,” or press Command-C.

If I clicked on the folder in the dock, it would open it. Instead, I find the application on my hard drive and “Get Info” the same way I did to copy the new logo. This time after I select that small icon in the upper left, I go to the Edit menu and “Paste,” or press Command-P.

To get the change to be reflected in the dock, I need to drag the folder out of the dock and replace it with the changed folder. I still see the contents of the folder, though, and that’s because it’s saved as a Stack and not a Folder. To change this, right click on the folder, and change it from Stack to Folder.

It should be noted that not all dock icons can be changed in this manner. The icons that ship with the Mac OS, such as iTunes, Mail, etc., are set so that you can’t simply copy and paste it away. You will need a program such as CandyBar to do that. However, that application comes with a $29 pricetag.
