Adding photos is easier than you think.

STEP 2Name your gallery and click "Add Gallery"
After adding the gallery, you'll get the confirmation that your gallery has been created by information in a yellow box with the message: "Your Gallery Title Here-gallery successfully created." You can show this gallery with the tag assigned (see double underlined tag on image below).
STEP 3Choose Upload Images from the options above the white box. From this window you'll be able to browse your computer to upload individual images. Browse for your image. Use the drop-down menu to choose the gallery.
STEP 4Upload images. You'll get a confirmation like the one below.
STEP 5When you have uploaded the images you want, click "Manage Gallery" from the menu items at the bottom left of the admin page.
STEP 6Choose your gallery. A window like the one below will open up, showing thumbnails and options for your images. From here, you can edit your photographs. As you hover your mouse over the image title, you have the following options: View, Meta, Edit Thumb, Rotate or Delete.
