How do I give credit to some image I included in my paper?

I recreated an image from a paper I liked (didn't use the same image to get out of the asking permission which could take a while). Now the reviewer asked us to give credit to the original paper. How do I do that? Is it okay to write that my image was 'inspired' from this other paper, as I didn't copy the image but used the image as a reference to create my own?
