Email signature images become extremely large after sending - html

Question

I've been trying to make an HTML signature in apple mail, which seems to be working fine for me. However, when I get replies to my emails, I see that some email clients make the image extremely large. I thought I found the solution by specifying the dimensions multiple times, and it seemed to be working fine for a while, but now it has started again.
So my question is: how do I make sure the image remains the same size?
