If you do still want to do it Braseco, until the new version arrives, open up jquery.fancybox-1.3.4.css
The path should be.
wp-content/plugins/easy-fancybox/fancybox/jquery.fancybox-1.3.4.css
Just delete from line 188 (.fancybox-bg ) to line 254 (#fancybox-bg-nw)
So that will be all the ids like below.
#fancybox-bg-n, #fancybox-bg-ne, #fancybox-bg-e etc ??
Then add this to the file as Ravan already mentioned.
#fancybox-outer, #fancybox-content {border-radius:10px;-moz-box-shadow: 0 4px 8px #444; -webkit-box-shadow: 0 4px 8px #444; box-shadow: 0 4px 8px #444;}
You can play around with the settings for the shadow and the border but this will give you rounded corners and a css shadow. The shadow and rounded corners wont be in present in IE8 and down though.
The end effect should look like this https://dragonartdesign.com/logo-design/stoneage
You might notice a little background around the image but that’s coming from the main style sheet not from the plugins style sheet. I just uploaded the plugin as a demo for you.
I have used the plugin on this site as well and it doesn’t have that background around the edges.

That’s a quick fix until this plugin is updated anyways ??
