I have tried creating an overirde directory for the email_template_welcome.html file to go in along with a new header.jpg, I have tried just simply replacing the header.jpg in the email directory, and I have tried complete renames and deletes.

Currently there is just the header.jpg file replaced with my own, no overrides attempted. The email is still pulling the zencart logo though. I did find what the problem seems to be but dont know how to fix or how I might have caused.

this is the file it should be pulling I thought

But when I copy the image location int he email it comes up with this
