If this is a VisualStudio setup project, make sure that you:
- include your Images folder and the images in it in your solution
- make sure you set BuildAction property for all images you need to
Content
- let your setup project also install content from the right project to the correct place in the file system where your application expects these images
- build you setup project and test if the installer installs the images as expected
(This is just a quick answer to perhaps get you started in the right direction. Your question doesn't seem all that clear, so perhaps I misunderstood the problem you're having completely.)
