How does one change the login screen background in Lion 10.7.4

Long time user on Onyx, great program.

I have used this function to change my login picture, it worked well, but there seems to be an opaque layer iver the top of the image making the colours dull. Does anyone know how to disable that?

Cheers

Onyx no longer has this option... 😟

Ver 2.8.1

Try Loginox at:

Ramon Tech and janthenat,

on one hand YES, loginox does it, but let us say: uncontrolled.

There is no documentation to make sure your background looks like the picture you were choosing for.

Example:

I used some of the pics being content of Mac OS like desktop background etc. They are of format 3200x2000 points.

Loginox takes them, but ... IT TYLES THEM.

if there would be some clear advices, one better could taylor the pictures for use.

I experimented by directly replacing appleLinen pngs in System CoreUI Private Framework.

It works, BUT ... i did not find out the correct resolution, and the three buttons are covered.

One could work with a png where this is cut out, e.g. with GIMP, BUT as long as it is monitor resolution and # of pixels (of picture) seem not to strictly correlate it is a long route of try and error.

Does anybody have any further ideas than just use loginox?

I like it BUT I do not like uncontrolled intransparency ending up in mystic results like the tyling.

I agree that using Loginox leaves the user without much control, apart from engineering images to fit. What I have done, and it seems to be working for my setup here, is put the Loginox app and three desktop images in a folder on the admin user desktop. The three images are identical except that I have 1 @ 4:3 (1024x768), 1 @ 16:10 (1920x1200) and 1 @ 16:9 (1920x1080) aspect ratio. They have been saved at the resolutions generally used here on our campus and they seem to scale fine for the odd larger or smaller display.

So after imaging a computer that requires a login screen background other than what was included in the image (relatively rare) I just login to the admin account, run Loginox and replace the image with the correct one. So far, so good... although I would still like to automate this. ;^) Maybe time to write a script to run at imaging time?...

I have read all posts, and understand the problem. I have the problem too!

Maybe, you could try this? (i'm not the best at this stuff, don't shout if i'm wrong!)
