Hi, Karen!
As long as you have your photo on your computer/device, you can post the photo directly onto the ECS website. All you'll need to do is post a new message on Chit Chat (like normal). Then, just underneath the white message box is a button that says "Browse." Click this, and your personal files will open in the dialog box. Navigate to where your photo is saved and double-click the photo. After that, just post your message, and the photo will be here! :)
