Then click on "Create" Button at the bottom of the page.

Step 5: Click on "Add Items" link to add photos.

Step 6: add photos one by one.
Click on "Browse" button to choose a photo
You can write your own caption for each photo, but you can also leave it blank.

Then click on "Add Items" button at the bottom.

You are done! Let me know if you are having any problem with it.
If you have lots of pictures to upload and do not have the patience to specify them one by one, you can go to
http://codex.gallery2.org/Downloads and download the Gallery Remote tool for your operating system. It'll make it a lot easier. Let me know if you need help on that.
