[NextGEN Gallery] Update to 1.7.0 failed

Hi,

I update to the last version 1.7.0 and now all my singlepics are not working but slideshow are ok.
In fact, when you click and the broken image, the real image show correctly in full size.

I got these errors:

Undefined index: x:xmpmeta in /wordpress/wp-content/plugins/nextgen-gallery/lib/meta.php on line 237 or 345

Notice: Undefined variable: args in /wordpress/wp-content/themes/techified/single.php on line 32

Please help me,

Thanks
