Imgur works fine. You just have to drill down to get the photo's address ending with .jpeg or .jpg (the actual address of the image).
And this: Scaling "imgur" pics: Add one of the scaling characters listed below before the ".jpg" in the image address.
Here are all the dimensions and letters to choose from:
s = Small Square (90×90)
b = Big Square (160×160)
t = Small Thumbnail (160×160)
m = Medium Thumbnail (320×320)
l = Large Thumbnail (640×640)
h = Huge Thumbnail (1024×1024)
Here is your Imgur pic. I found the .jpeg version of your pic's address and scaled it to "l".
