Can't upload pictures into CRM Newsletter

I can’t upload pictures into CRM directly to then embed them into newsletter body. According to our developer, CRM isn’t meant for it and we may only upload pictures somewhere else and only embed them as links to outside servers.

The problem is, there is that menu for uploading pictures in most newsletter editors!
So the function is there, but somehow it doesn’t work.

Also when we tried to upload the pictures directly into CRM, they were embedded into newsletter template, but when we sent the newsletter the pictures just disappeared leaving empty space where they were supposed to be.

Would anyone know how to help me deal with this?

I don’t know if posible… But why if you try to embed base64 encoded images?

Thanks,
