Tracker for UI bugs

I need a tracker, but more specific a tracke开发者_如何学编程r for UI issues. An alternative to JIRA o PivotalTracker. I need to post some screenshots, and make annotations on them. I need basically a practical tool for report UI bugs. Anny suggestion? Thanks in advance

You might also have a look at JIRA in combination with the screen-sniper plugin https://plugins.atlassian.com/plugin/details/19613

Almost all tools allow you to attach files. Many show graphics files in-line. Choose any of those.
