All right answering my own question :
I just found a bit of CSS for the gallery image that is not a link and for a gallery image that is a link and specified the cursor I wanted on it
/*custom cursor 1*/
html, body {
cursor: url(https://juliettebinet.fr/s/Mouse_final_45.png), auto !important;
}
/*custom cursor 2 = text links*/
a, h1 a, h2 a, h3 a, h4 a,
h5 a, h6 a, h7 a, h8 a, h9 a, {
cursor: url(https://juliettebinet.fr/s/Mouse_final_hover_45.png), auto !important;
}
/*custom cursor 2 = image links*/
.sqs-block-image a img {
cursor: url(https://juliettebinet.fr/s/Mouse_final_hover_45.png), auto !important;
}
/*custom cursor fix on gallery images that are not link or lightbox to stay 1 */
.sqs-gallery-block-grid .slide .margin-wrapper a.image-slide-anchor {
cursor: url(https://juliettebinet.fr/s/Mouse_final_45.png), auto !important;
}
/*custom cursor 2 on gallery image wiht lightbox */
.sqs-gallery-block-grid .slide .margin-wrapper a.image-slide-anchor[href] img{
cursor: url(https://juliettebinet.fr/s/Mouse_final_hover_45.png), auto !important;
}
