Trouble connecting own image/node....
You might want to ad, that Self-Made Icons should have a white background, better said a background at all! If you try to import a png with transparent background you will find it very hard connecting your self-made node, as in this case the center of the image will be used as refernce point for the arrows to lead to. With other words, dont use a transparent bg, or arrows will be pointing at the center and not at the edge of the grafik.
