"Oh No! Oh no, that isn't a valid image!"

I'm trying to post my drawing: http://imgur.com/a/o7zdi to my forum posts to the right, and it is 325x325pxs. I was hoping to find out what I've done wrong?

[.Spyro] The url needs to end in an image extension, such as .gif .jpg .png etc

Right now that's just a link to a page on imgur

Oh geez, that's totally it. Thank you so much~~!

[.Spyro] No problem! That's a really easy thing to do with imgur for some reason :x
