+The image object is for adding more advanced backgrounds.
+It also provides a :shrink() function, where you can shrink the images to smaller ones. This functionallity is fully provided by the blittle library created by Bomb Bloke. I did not ask for permission to add it into the framework. If the creator wants me to remove the blittle part, just text me on discord!
+
+The image object is still not done. in the future i will provide more image formats.
+
+Remember image inherits from [Object](objects/Object.md)
