You first need to have a user name/ password to this site. Go to "Register" on the main page. After that go to "Personal Lockers" Scroll down and find your username and click on it. Once in your locker you will need to start off by creating a folder. Once you create a folder you can now add files to it by selecting "Click here to add new files in this folder".

Once you do this you will get a screen "What would you like to do?". You want to select "Add a New File." You will then need to locate on your computer where the file is (or in your case a picture). If you don't know exactly where the file is you can hit "Browse". Once you have located the file make sure you target the file in the empty space next to "Browse". Hit "GO" at the bottom. Waala! You then can add more files to this folder or create more folder for more files!
