Texture change for sunglasses?

Where can I find a script to change texture on sunglasses (just on the lenses)? I have a script that works but ya gotta click on each lens and its actually impossible to get to the lenses unless you standing on a posing stand.

Somebody suggested I use fairly standard listen script with a chat message on an unusual channel...That sounds exactly like what I need

Anyone got one VERY easy to use or hints where to get it?
I just need to be able to change two textures.

What you need to do is send the key of the new texture to user via a either a chat message or a linked message from the root prim.

The script in lens will then call llSetTexture passing it the id it has just received.

thank you for yor reply Newgate, but do you have any idea where I can find a script like that?
I'm not a scripter at all I'm just a dumb designer

The sort of thing you are after has been previously covered as a window blind script here
