picture not animating on a mesh

Hey forum, i’ve been trying to fix this for at least 3 hours but i couldn’t find a way. maybe you can help me out.
im having a mesh and wanted to put a picture on it to animate it but somehow it only shows one solid color. when pressing play it switches the colors but remains as colors and not as the wanted picture… i tried it on the plane right next to it and that one worked perfectly fine.

Did you set up UVs for the cape?
