To sign up click on the small Yuku logo upper left. you will see 'Sign up now' button. Fill it out, choose a pinname and password, go to your email after signing up, you should have recieved an email that you copy and paste the validation number of your membership into the confirmation page. they do this for stopping spammers.
Look above your post for the small mountain icon. That is the box you put any photo url in to. Or if you upload your photo in your "yuku" member album, you will see them when you click on this icon. Just choose the one you want in your post.
Or you can just copy and paste any of your photo urls into the box provided after you click on the image upload icon. Yuku does the code for you. Click on ADD FROM URL to add your own from your off site photo storage.
Please don't use an album site that does not allow bandwidth sharing or it will be a red X. Upload them to your yuku album instead if that is the case.
Or if you already have your albums elsewhere, you can just right click choose copy, and paste the photo straight into your post. It's so easy here! No code needed done this way.
Everyone please clean up your own red X's. Thanks. It slows down the board as an error. So be responsible with your graphics. Posts with red X's will be removed.
