Adding a signature on image caption

Hi,

Is there a way for me to add a signature photo instead of the persons name on a photo caption?

 Basically this is an image block with a collage effect. So I know it's just text you can type on it, but my client wants her signature on there.

If you can help this would be great.

Use CSS like this...

.image-subtitle-wrapper h4 {
    background-image: url(https://beaverhero.com/wp-content/uploads/2019/06/trees-3464777_640-min.jpg);
    color: transparent !important;
}

@tuanphan THANK YOU VERY MUCH!!!! You're a lifesaver!
