To hide link

Thank you it works but finally is there a way to remove the links on the album covers to use only the widget?

This can by done by custom css:

.wppa-album-cover-link {
display:none !important;
}

Thank you but it also hides on the widget

This will do:

.wppa-album-cover-link {
display:none;
}
.wppa-upload-widget.wppa-album-cover-link {
display:block;
}
.wppa-create-widget{
display:block;
}

Even better and simpler:

.wppa-cover-box .wppa-album-cover-link {
display:none;
}

thank you very much for the help, it works.
