This is deliberate behaviour as a caption could be of significant length and space on mobile devices is limited.
If you want to reinstate the caption try editing magiczoomplus.css (in your Site folder) and look for:
Code: Select all
.mobile-magic .mz-expand .mz-image-stage > figure .mz-caption {
display: none !important;
}
I also see:
Code: Select all
.mz-zoom-window.mz-expanded > .mz-caption {
display: none;
}
