You can add pictures by using imgur. Here's how to do it.
First, go to imgur.com.
Then make an account and log in.
Then click on the green 'New post' button on the top left of the screen.
Then, either drop the image you want to post on the left side of the square or paste the image/url on the right side.
Give your post a title
Add extra pictures by scrolling down and clicking on the 'add image' button
Then click on 'post hidden' if you set in on pubic, everyone will be able to see it.
After you clicked 'post hidden' you gt a link you can post that will lead others to your pictures so they can see it.
I don't know about the value though. Good luck.
