You definitely see images of Jesus hanging on the cross as the central image in Protestant churches behind/above the altar in Europe.
It is pretty much impossible to make any simple statement on this matter - or most others in the field of religion - because a label like "Protestant" covers many different traditions and practices. Sometimes even within one single denomination. And "Europe" isn't exactly monolithic or homogenous either In the university town in Scotland where I studied there were two Anglican churches: one "low church" in the evangelical tradition, the other "high church" emphasising Catholic theology and liturgy. "Bells and smells"! One day I attended a high mass for a festival in the "high church" and happened to sit next to an Anglican priest from the other end of the spectrum. At one point in the liturgy which involved a lot of incense and genuflection my friend nudged me in the ribs and whispered in my ear: "When I come here I always have to remind myself that not only are we the same religion - we are in the same church!"
