How do I set the Priority Icons back to default?

[Bill Goodall]

We upgraded from JIRA plus JIRA Agile to the new JIRA Software product and got some nice bolder icons.  Then we agreed to look at what other icons were available.  We saw the Chevron based icons and decided to try those. Now we want to go back to the bold ones. However only the newly selected icons show in the menu. How do we get back to the bolder icons that were in the upgrade?

Check the contents of the 

/opt/atlassian/jira/atlassian-jira/images/icons directory and take proper filenames to put for each priority icon.

There are a priority icons available as gif, png and svg
