Everyone has to start somewhere! Your link to your Flickr page does work above. You can link to your pictures direct in here as well. In Flickr select one of your pictures and click the "All Sizes" button that is above it, select the size required (generally max 800 pixels on the longside is prefferable), then below the picture you will see two boxes containing HMTL code for your picture. Select all of the text in box 1 and then use the following link to obtain the code to post in this forum to display your picture:
