To detect such a tampering you should add your graphical files as resource within your application (or load from another assembly) and use Strong-Name signing. Even if it is not completely secure, it should prevent the most ones from altering your resource files.

You could embed the images into resource files that get included in the exe.

The easiest way is to use the images as a resource.

If you don't want to do that for any reason, then you could also calculate a cypher of the jpegs (maybe MD5) and check them against the one you previously stored in the code while loading the load program (form.load or whatever).

You could sign your files this way no one would be able to change the files without having your certificate.

this might be overkill and it depends on how mutch security you want else just place the images as resources.
