Image File Hosts have no adult ads and friendly with .gif

Hi guys, can somebody recommend me some image file hosts (can be monetized)
- No adult ads (The first priority. I found a lot of image file hosts like that. My visitors may not leave my site because of this)
- Friendly with .gif image. It means that the image is able to be animated when it is embed on my website
- Stable running and fast loading image.
If can, store image forever :D

Thank you guys :P
