Hello Omar,
I see that your post is from 2015, but I had the same problem in 2019  :)
However I found a solution and I'm sharing it for someone who is experiencing the same issue.
In *Ir_http.py* there is a method  called *binary_content*, which returns a binary field content and some other info. You can use it in any model or controller with the following import:

Lyubo.
