Having the same problem. Added the NextGEN widget to the sidebar, put images in a folder in wp-content/gallery, set permissions on folder, and all I get is circular animation. There is another folder called thumbnail in wp-content/gallery but I don’t want thumbnails I just want photos to change every 10-15 seconds. Further, it says slideshow and I don’t want a title, so how do I remove the word slideshow? This is on the first page of the site http://www.markdex.com
Thanks for any help that anybody may provide!
