Item9183: Plugin is adding a empty first image when using lightbox as frontend

When i use %IMAGEGALLERY{frontend="lightbox" size="small" include=".(png|jpg|jpeg|bmp)$" skip="0"}% then click the thumbnail, the overlay appears and showme N+1 images, where the first is an empty image.

Checking the code, i found that when the frontend parameter is set to lightbox and no custom header parameter, the plugin set the header parameter to:

    $this->{header} = "<noautolink><div class=\"igp jqSlimbox {itemSelector:'.igpThumbNail', singleMode:true}\" id='igp$this->{id}'>\n<a name='igp$this->{id}'></a>\n";

And the Slimbox JQueryPlugin take the

"<a name='igp$this->{id}'></a>\n"

as the first image to show in the overlay.

To fix that problem you have access to the foswiki server, go to the foswiki-root/lib/Foswiki/Plugins/ImageGalleryPlugin/Core.pm line 290:

     $this->{header} = "<noautolink><div class=\"igp jqSlimbox {itemSelector:'.igpThumbNail', singleMode:true}\" id='igp$this->{id}'>\n<a name='igp$this->{id}'></a>\n";

and change it for:

>     $this->{header} = "<noautolink><div class=\"igp jqSlimbox {itemSelector:'.igpThumbNail', singleMode:true}\" id='igp$this->{id}'>\n";

the diff:

diff Core.pm.org Core.pm 
290c290
<     $this->{header} = "<noautolink><div class=\"igp jqSlimbox {itemSelector:'.igpThumbNail', singleMode:true}\" id='igp$this->{id}'>\n<a name='igp$this->{id}'></a>\n";
