just test to see what it is suppose to look like

the overlay covers the entire image on my forum

sorry… cant be close???

are you talking about the lightbox with opacity?

please check this:  http://codex.simple-press.com/codex/installation/changes/theme-and-templates-5-3-0/

the section on popup dialogs…

and a link would be helpful…

I resolved this issue with some CSS

/*forum image*/
.ui-widget-overlay {
background: rgb(7, 7, 7) !important;
opacity: .50 !important;
filter: Alpha(Opacity=50) !important;
z-index: 1 !important;
}

yup. pretty much what I pointed you to… though if you have a z-index of 1 with !important, likely battling your wp theme for control…

nice work…
