Mick - go to the picture on POE that you want to put in a thread, under the pic you will see an ID number( i.e. ID 1135774). Note that number down. Go to the thread you wish to insert the picture in, then follow Ron's instructions. The "tree icon" is on the right hand side of the tool bar below, next to the smiley!
Hope that we will see your pic in this space shortly
