Upload images on external hosting?

[nier3]

Hi, I created this thread:

http://mybbhacks.zingaburga.com/showthread.php?tid=1584

about upload images on external hosting.

I have read answers (API etc), but I don't understand how to proceed.

For example from Box.com:
http://developers.box.com/get-started/#u...http://developers.box.com/get-started/#uploading-and-d

I have to add this code in Xthreads? Thank you very much
