Link to one picture using NextGEN:

1. Go to Gallery > Options > Effects
2. Notice which effects class you have selected ( thickbox, shutter, etc.)
3. Go to Gallery > Manage Gallery > Gallery where image is located
4. Mouseover the "View" link, then COPY link address.

Now use this as the format: ( In this example I used the shutter class )

<a class="shutter" href="" title="Image Title">Image Description</a>
