Installing Icons In the Menu of programs can be easily accomplished if you follow a few simple rules. All ICONs to be placed in menus must have ICON resource ID numbers between 256 and 511, and their corresponding ICON number for the menu is the ICON resource ID number minus 255. This proceedure involves using ResEdit, as always work only on a back updisk with a copy of the program you are changing. Never use ResEdit on an original copy program, unless you like to live dangerously, like never backing up your hard disk.
1. Place all of the Icons you want to place on the meus in a resource file. Or create the Icons in ResEdit and save them as a resources file. Using Get Info from the File menu to set the Icon resoure ID number for of the ICONs you have created to between 256 and 511. Be sure you make notes of all the ICONs their ID numbers and their menu numbers.
2. Open the program in which you want to place the Icons and open the Icon file with ResEdit. Make note of the Icons already in the program and their ICON resource ID numbers. In your ICON resource file change the ICON resource number of any of your ICONs that will conflict with the ICONs already in the program. Select the ICONs from your ICON file and paste them into the ICON resource file of the program.
3. Open the MENU resource for the program and the individual MENU you want to place the first numbers into. Each menu has a separate resource file, MENU ID 1 is usually the Apple Menu, MENU ID 2 is the File menu, etc. Scroll down to the menu item you want the ICON by and change the icon# from 0 to the ICON number for that ICON (remember this is the ICON number not the ICON resource ID).
4. After plascing all of the ICON number next to the appropriate menu item, close the MENU resources you opened and when asked if you want to save the changes to the program click yes and your changes will be made in the program.
5. Quit ResEdit and open the altered program. You should be able to see the ICONs in the menus if not check you proceddures and try again. The only reason it usually may not have worked is placing the wrong numbers in the icon# for the menu item.
Enjoy Putting ICONs on your menus, I hve done it to several programs and it makes them much more unique and interesting to work with.
