display nav arrows in gallery images but not in single images in blog post?

Hi and thanks for a great plugin.

I just installed Fancy Gallery after already having an install of NextGen active. I used NextGen to create my image galleries but would like to use FancyGallery to display them. Everything appears to be working fine with the exception of one thing:
I want the posts with a single image to NOT have any nav arrows and the gallery pages with a NextGen Gallery placed in the post to display nav arrows when a thumbnail is clicked so a viewer can go through all of the images on that page one-by-one. I am struggling getting this scenario to work.

I have the GALLERY>OPTIONS>EFFECTS>Java Script Thumbnail Effect in NextGen set to NONE. When I go to my home page (www.flominton.com)and click a single image in one of the blog posts, the Fancy Gallery works perfectly and displays the image in a lightbox. When I go to a gallery page (http://flominton.com/?page_id=115) and click one of the thumbnails, the image displays perfectly, but there is no nav arrow to see the next image in the gallery.

I went back to FANCY GALLERY>OPTIONS and tried ticking “Consolidate single images in a post to one group so the user can navigate through them”. This inserts the nav arrows perfectly in the gallery page, but the problem is it also puts a nav arrow in the post with the single image and connects all of the single images on that page and into the rest of the NextGen Galleries, which I dnot want.

I would like to only have FancyGellery display the nav arrows if the post or page has a multiple image gellery and not display the nav arrows for an image that is the only image in a blog post.

Can you tell me if this can be done?
Thanks again for your great plugin and I appreciate your help very much.
