When you sign up for an unmaintained account a gallery is automatically created for you. To upload images start by selecting the Image option from the main menu at the top of the page. Your username will be the name of your gallery, find it on this page and click to enter your gallery. To upload an image look in the bottom right corner for the Add Picture option. On the resulting page select Upload Image then select the Browse button to find the image on your computer. Add a Friendly Name, something short and click Upload. You can then add a longer description as well as tags ( keywords for searches, separated by semi-colons ) if you wish and click Save in the bottom right corner. Give your page a minute or two to update and the image will be added to your gallery.
