You can upload your own photo to be used as your online identity quite easily. Here's how...

Log in to the site as normal.

From the Navigation menu, Click on the My Account link

You're now in your Profile page where you can edit various details about yourself. When you register, you're given the default image for any member - the Big D you see on the right. Click the Edit button to get access to the page to change this.

Scroll down the screen a bit until you see the Picture panel. The Upload picture panel should be empty. Press the Browse button and navigate to where you have apicture stored on your own computer. It's best if this has been cropped to around the maximum size allowed - 85 x 85 pixels, but if yours is larger than that, it will be scaled down automatically.

Find your image - it can be an image file in jpeg, gif or png format - Select and Open it.

Back in the Picture panel, the file should now be listed.

Scroll a bit further down the screen again until you see the Save button. Press that and your image will be uploaded to your personal folder and saved as your identity on DelphWynd.net.
If you want to change the image at any point you can do so by following the same procedure.
