Changing Icons problem?

[notwelby]

Hi there,

I know how to change icons but I'm having problem with the type of file. I've managed to change one using the rsrc file type but no other type will work for me such as icns, png or tiff. This is probably something easy. Do they have to be converted into rsrc or is it the OS version I'm running?

The easiest way to change an application's icon is replacing it through the Get Info window (copy and paste a new one). The downside is that method only works from application-to-application.

But if you want to change it using any ICNS file, the app's icon file is located in the app's /Contents/Resources/ folder (e.g. Firefox.app/Contents/Resources/). It should have the name of the app itself or simply icon.icns.
