Hi,

I am looking to customize the Nextgen gallery slideshow like you see this : http://www.cosmopolitan.com/hairstyles-beauty/skin-care-makeup/4-5-beauties-of-the-week-gwyneth-paltrow#slide-2

I want to customize the slideshow in a the same way.

1. I want to add title and description for each image.
2. I want to add left arrow and right arrow that you see in this page i have mentioned.

I have tried many times but could not get the same.

Please let me know hot customizemy nextgen gallery slide show to like like this.

Regards,
ashish Kumar
