Thanks for input and suggestions . I'll probably skip the zipping. Indeed the PNG and JPG formats are great. I think in this case I had some problem making it work with PNG, while a BMP-file behaved well albeit being huge. Anyway. First priority is to create something executable and playable at all.

I'll have a look at the polyline and bezier suggestions.
Indeed my approach while getting the job done started to get cumbersome, as more points were added . In fact I spent 100 lines of code just to make that image. A polyline with array could no doubt simplify things. And more curvy lines can add some allure.

There's still some polishing and adding of functionality to do so nothing can be presented yet. Hopefully a new thread can be started for the new project in the coming week(s).
