For nice graphics you can go yo http://www.photobucket.com and http://www.glitter-graphics.com/ 

At photobucket choose the "Find Stuff" tab at the top of the page, type in what you are looking for in the "Search" blank on the right hand side of the page, if anything is found your results will pop up. If you see something you like, left click on the picture itself, not the (by....?) link. When the picture appears, scroll down the page. You will see several codes. You want the last code which will be listed...IMG Code-Forums and Bulletin Boards. If you left click on it, it will automatically copy it. Then come back to the BB post you want to put it in and right click on the posting window. you should see your menu bar pop up, just click on paste. When you're done, hit post. Back on the BB you should be able to see your post. The picture should be there, if not.... hit "edit" and repeat these tips with a different picture.

Note: Sometimes  you might get an "error' message and the explorer window closes. But you just log back on and go back to the BB, you will see the post actually went through ok.

Now to do the Glitter Graphics site you need to left click on a picture, for starters  left click on seasonal, there is a list to the left that says at the top Navigation, go down it and find Fourth of July,  left click on it, on the page that comes up, first row , first picture ,  left click on it on page that comes up below picture it says download image, left click on that. On smaller screen that comes up, right click, then on screen that comes up left click on copy, click off at x's at top of screen , go to where you want to paste., left click then right click. On screen that comes up left click on paste and you should have your picture where you want it. Should look like this
