Doesn't sound like a deployment issue. More like how you can Develop the app. So try the app development space.
A possible solution, assuming your images are not confidential
If your data is sensitive, then you can import these images into your project image collection and similar to above, use java action to put them in the right place.
Are these static images? If you create a folder in theme/web folder and add the images here, they will be part of the deployment package.
