What is the diiference between statues and stained glass windows?

I have seen many times on here that the catholics are accused of worshipping false idols because they have statues and pictures of Jesus, Mary and saints in their churches.

I just asked the question “Do protestant churches have stained glass windows? What do they depict?”


Most of the answers were yes, they depict saints, biblical scenes etc.

Can someone explain to me what the is difference please?
