permission

[steven vollom]

I just installed Digikam in Jaunty kde 4.2.3.  It said I did not have 
permission.  I typed sudo digikam into a terminal and got the following:
steven at Yeshua:~$ sudo digikam
Error: "/var/tmp/kdecache-steven" is owned by uid 1000 instead of uid 0.
Error: "/tmp/kde-steven" is owned by uid 1000 instead of uid 0.
digikam(5182) Digikam::DigikamFirstRun::DigikamFirstRun: 
"/home/steven/Pictures"
steven at Yeshua:~$

What do I do and how do I do it to get appropriate permission and permissions 
fixed?  Thanks.  A neighbor was burglarized this morning and I took pictures 
for him.  Thanks!
