I migrated with a project from Bitbucket to Github and I can not find a way to attach a file to an issue (ex: screenshot, specs, etc)

How to do it?

As of December 7, 2012, you can attach images by drag/drop or use a file chooser. See https://github.com/blog/1347-issue-attachments for more details.
