Thanks for the quick reply. I implemented the above code and it showed a red x where the image should be.
I tried to alter
var div=this.CreateItemDiv(c,null,(c.Title||GalleryLocalize.DEFAULTCATEGORYNAME)+" ("+c.Photos.length+")",c.Photos[0].Thumbnail.substr((c.Photos[0].Thumbnail.indexOf("/",2)+1),c.Photos[0].Thumbnail.length),128,128);
to
var div=this.CreateItemDiv(c,null,(c.Title||GalleryLocalize.DEFAULTCATEGORYNAME)+" ("+c.Photos.length+")",c.Photos[0].Thumbnail,128,128);
and now the image is showing up, but the scaling is not correct so the picture looks very weird. I must not have the code right.
Thanks for any additional help you can provide.
