Thanks for downloading NextGEN Gallery Optimizer!
Firstly, you'll need to get yourself a copy of NextGEN Gallery...
Once you've activated NextGEN Gallery on your plugins page, look for a "Gallery" tab at the bottom of your left sidebar in the WordPress admin.
Here's a little quick-start guide for you...
1. Go to Gallery --> Add Gallery/Images
Click the "Add New Gallery" tab, enter a name for your gallery and click the "Add gallery" button.
2. Click the "Upload Images" tab, click the "Select Files" button and choose which images you want to upload from your computer, select the gallery you just created from the "in to" dropdown menu, and click the "Upload images" button to begin the transfer.
3. Finally, to insert your gallery, just create a new post or page (Posts --> Add New or Pages --> Add New), type the shortcode
[nggallery id=1] into the editor, and click the "Publish" button on the right to save your changes.
And that's it! Navigate to the page you just created and your gallery should be live!
If you'd like to optimize this for speed, and/or add the Fancybox lightbox effect when you click on your gallery thumbnails, simply activate NextGEN Gallery Optimizer from your plugins page and check the Fancybox option on the (NextGEN Optimizer) settings page.
After you do, just go to Gallery --> Options --> Effects, select Custom and enter:
class="myfancybox" rel="%GALLERY_NAME%" to complete the installation.
Hope this helps!
