hello Donna,
below is a posting I put up in the veggie plot section for Guy, it should cover what you want to do ok too:
to put pics or vids on you first need to start up a photobucket account ( if you don't already have one ? ), it is free and is a handy place to store all your digi pics and vids. Then, when you have got your pics/vids on there, if you want to put a pic on the forum just look above the bit you type a reply to a post in ,you have the little smiley things then above them you have the square boxes. To put on a picture you need the second one in ( insert an image ). Left click on the box once and you get this appear img][/img] ( there should be another bracket [ at the front , but if I put that in the text it tries to load a piccy up ) . You then go to your photobucket album and chose the pic you want to place on the forum . Below each picture there should be 4 lines of choice, you want the bottom one ( img code for a picture ) left click on that line and you will get a little yellow box appear that says ' copied '. Now go back to the forum post and place the curser bar between the central back to back brackets of the img][/img] (remember there needs to another bracket [ at the front end..) and hit the left mouse button once. Job done , if you then hit preview you should see your picture appear. If you want to put the video link on the forum ? go to the third box, the one on the right of the insert image box. Click that once and then do the same as for the picture . It takes ages to write it out , but only a second or two to do , very simple mate . It is just a pain at first ...... I hope at least some of that made sense ?
I hope that helps a bit ? If you need anymore help just shout ...I won't hear you, but shout anyway...(it always helps me

)
cheers
