API Problems

Hello, I've been trying to use the API of this site but when I try to access any image, for example http://behoimi.org/data/sample/c6/38/samplec638427d6668437624cb33b48594634c.jpg

I get this result:

any idea ?, thank you !.

Edit, sorry. That's the bit of code to keep people from randomly using up bandwidth because they are too lazy to use an image hosting site. Try setting a referrer.
