Urgent help!

Try going to "Uploads" in the banner at the top of the forum

 

It's also very easy if you make a PhotoBucket account, you can just paste the link, highlight it, click Img, and it shows up. ^^

 

Upload a picture, then copy the link that says Image. Then paste the link to your message.

 

Now with the new thing, you can do it in the Reply box.
