How to open a smalltalk image in squeak?

Super noob question here. Seems basic but I'm not understanding how to do this.

Someone sent me a smalltalk program "program.app" and now I want to open it and run it in squeak.

How do I do this? I have squeak open on my ubuntu desktop.

It depends on what exactly your "program.app" is. In general you need a virtual machine (the squeak executable suitable to your operating system) and an image file (the memory snapshot including the Smalltalk bytecode of all the methods) to run. You would then run the VM with the image as a command line argument from the shell, not from within a running Squeak process.

Note: if you do not trust the source of this "program.app", consider the risk of running an unknown program. A Smalltalk image will execute code without any input from your side once started.

If program.app is a directory, search for an .image file in there. Once you have located the image file and your Squeak VM executable, run the VM with the image as a command line argument:

squeak program.image

If program.app is a directory it could also be a "bundle". That is, it could bring both an image and a VM to run it. For example, the Squeak All-in-One bundle downloadable from squeak.org includes one image file and three VMs: one VM for each major platform, plus start scripts in the top-level directory. If program.app includes a VM, it may work best to run the image with that VM:

program.app/path/to/squeak program.app/path/to/program.image

Maybe it even has a squeak.sh start script, like the All-in-One bundle.

If your "program.app" is not a directory, please ask the person from whom you have obtained program.app what that is and how to run it. If it is the renamed image file already, run the VM with it: squeak program.app.
