wrong instagram photo url

Hey,

I’ve tried to post instagram photo without any plugin, just by pasting instagram url into text area, but it doesn’t work.
I looked at page code and found out that it changed url of the image.
For example, instead of something like this http://distilleryimage1.ak.instagram.com/db427156d52411e2b4f022000a1f9ac4_7.jpg
it shows this
http://distilleryimage1.ak.instagram.com/db427156d52411e2b4f022000a1f9ac4_8.jpg
last symbol has been changed
