To use the smiley again, instead of having to go find it all over again, I usually copy the image with copy image, then paste it to a word doc (right mouse click the picture) so I know what it looks like. Then with view image copy the link right below it on the same doc. Then I can just cut and paste it when i need it.
Right click on a smiley that you like.
Click the view image option while holding the Ctrl key (so it opens in a new tab or window)
Copy the URL (web address) of the link by highlighting it and right clicking and chose copy.
Come back to here to where you want to post
Paste the image into your response by right clicking in the editor box and chose paste
Then highlight the URL that you just pasted (hold your mouse button down and drag the cursor to highlight)
Then click the Img button that will put the
tags around the url
Now your smiley is in the post.
Go ahead give it a try.
eta: There is no way to put the smileys on the site for a quick "grab" other than adding them to this thread and bookmarking this thread on your browser. Your other option is to save the URLs in a word doc as Queen Mum suggested.
