Here's an image from the pheedo web tracking ad thingie whatever:

[larsi@quimbies ~/pgnus]$ file /tmp/a
/tmp/a: GIF image data, version 89a, 1 x 1

(image-size (create-image "/tmp/a") t)
=> (30 . 30)

And inserting that image into the buffer yields an empty 30x30 box:

(put-image (create-image "/tmp/a") (point))

In addition, the rest of the text in entire buffer starts shaking and
shivering, and the cursor disappears.

So something is just not right, I think.

Here's the GIF in question:
