Thanks for using NVN!
Do what you've just done but...
1) post it in the house and garden section
2) to drop a link in, just copy and paste it and the site will make it live
3) to add a photo, look at the bottom of the "white" box that you type you text into when you're actually writing the text and there is a tab below it called "add a picture of attachment", use that to add a picture
Does that make sense?
Any problems shout!
