This is a logo i created in photoshop for the login panel logo. yes i know. The fire (at the top of the image) is cut off. Thats because i had to have the same size for the perfect logo. for mac osx users to have this as ure mac login logo u have to:
1. change the name of the image file to applelogo.tif then u have to go to this:
/System/Library/CoreServices/SecurityAgent/Contents/Resources the current applelogo.tif must be copied to ure desktop then changed to applelogo.tiff-backup and pasted back into teh resources folder. *You may have to enter ure password to authentify it. then place the applelogo.tif i told u to convert it to at the beginning into the resources folder. *you will have to authentify it and click replace. this will replace the current applelogo.tif but DONT WORRY u have the back up. Then when u log in ull see the firey apple mac logo.

2. To get rid of it all u have to do is copy the file applelogo.tif-backup onto ure desktop and change the filename to just applelogo.tif and paste it back. You will have to replace and authentify it again and it will be restored to original state.
