problem with Better Minify

Hello,
I’m testing your plugin and I’ve got problems with Better Minify plugin: http://ww.wp.xz.cn/plugins/bwp-minify/

The Lightbox effect works but images (next page/previous page arrow, close button) do not show. If I click on right on the image, the next image is showing correctly. Don’t know if it’s easy to correct so I ask 🙂
