Looking for script that changes remote prim textures

I have satellite stores with a sign that shows the same information. I would love a script I could use at the home HQ business where if I change a texture on the main sign there, it will change it automatically at all the other locations. Also as an added bonus would love to be able to change out the landmark or other objects given when someone touches that sign. I know it's possible because I've seen it done in game, but don't know where to find this script or what it would be called. If anyone has anything I could use, I would greatly appreciate it. Thank you!

I am currently building something almost exactly like this for Axle Castro. It is an exclusive build, but get ahold of him and I am sure he will let you know once they are released.

I can think of at least two ways to do this. One involves an off-world server which may not be available.

There are a number of more or less stable entirely in-world options though. Rez your parent prim. Find it's key.

Put in scripts for receiving and dealing with emails for handing out landmarks and things.

Put notecard with key (or other means, e.g. description field) into satellites. Have the scripts there email home when rezzed, and when touched for a landmark etc.

Decide if you want to push or not. If you do you need the parent prim to store keys of children, when it's texture is changed, it emails out the textures (this will take a while, even with a script farm, depending on how many you've got). If you don't push, you'll have various different displays in different places for longer, but each time you send a "give out a landmark" message from the child you could activate a timer for say 3 minutes, include the current display key and if it's different (i.e. out of date) the parent emails the new key back.

The actual scripting is a bit fiddly, but not too bad. The notecard/key in description field makes it easy to change the parent prim's key if you accidently delete it.

The system that I am in the final stages of testing for Axle is a prim server based adboard system. It has many options, including the ability to turn off renting and use it as a server based sign system. Contact him for more info.
