Postimages.org is the best I found. You can make an account (optional), so you can always delete a photo later, if you want. Photos also never expire like on most other services, if you click that option. Highly recommend this website.
When you use the site, use the Direct Link and copy that over to this forum. Then select and push the image button in the bar above this (the 7th icon, farthest to the right). If you need help, just send me a PM.
The problem with Imgur is that all images are put out in public, I believe. Everyone can see them and use them. Companies watch those kind of websites to use your images. Personally don't recommend using them.
