Hockneynut!.. welcome aboard... and with a cracking shot to start, fun software that hey. (i'm really quick at making tea now, as you can see from up above there somewhere) ..and your son is VERY rock!
What are you using to resive images at the minute? And i'm thinking that the reason your pic attached as a thum as opposed to a larger image would be that a lot of people use flickr / photo hosting websites to upload pictures to and then copy some code across that puts the picture into your post. Do you have a
flickr account or something along those lines?
