Pronounced image-er, it's a really good image hosting website, and it's been around for a few years now. Try it, it's fast, easy, after you've uploaded the pictures which you can do simply by dragging them onto your browser, there are resize and crop tools built in if your pictures are too large.
Also, they give you a forum link to copy and paste right there.
I checked out a little more info. They promise to keep the pictures up as long as they are viewed once every 6 months. But that's just the minimum, they may keep them up longer.
(Also, I don't know if this is the right section of the forum to post this in, Mods feel free to move it if it is incorrect.)
