Utility for explore a image file

That is what the BAR does, it shows you the contents of the image file.  Letting you see what files, and size and last modified date, and what tape it is on.

What more are you wanting to see that you need a different way to look at it?

You can use BAR if you have the image available (unexpired image file) but If you want to see a image on a duplication backup, you can't use BAR without import the image file.
The reason why I need a utility for view  what contains the duplication job and see If the duplication have the correct information before send offsite.

Is there any reason why you don't want to do an import?

You want to verify images on a duplicated, unexpired tape?
Why not use the verify option in the Catalog section of the GUI (or bpverify from cli)? Using the verify utility will mount the tape and compare contents with catalog info.
Alternatively you can read up on how to use tar to read tapes. Admin Guide II has this section under Reference Topics:
Reading backup images with tar

If that still does not convince you, promote the duplicate to primary and test restoring from it.
You can then promote the original primary again before sending the duplicate offsite.

If it's not in the catalog, use /usr/openv/netbackup/bin/tar

I just want to see the contains (In Files) of a image file. Like a Windows Explorer
I cant use a Import option If I add the incorrect files, we need to import other images until import what we need. I dont want to add many  images to my db.

I just try to find a utility for example: you type the image name and then you can see the contains in file of that image.
Example:
server01_123456789_image 
C:\hello.txt
C:\Windows
C:\text.jpg

That what I need. Its possible do this in VERITAS NETBACKUP???

Do you want to read the physical tape or view the contents of the image?
Backup ID (image name) is the same whether original tape or duplicate tape. 

I can see you getting frustrated trying to explain what is it that you need and seemingly all of us battling to understand...
Let me try again to understand: The image file that you're referring to (server01_123456789_image) - is this the actual disk backup (tar) image and not the catalog image file on the master server under ..db/images/<client>/.... ?
The disk images on my lab system have filenames like these:
mariannelt_1262938740_C1_F1.1262938740.img
mariannelt_1262938740_C1_F1.1262938740.info
mariannelt_1262938740_C1_F2.1262938740.img
mariannelt_1262938740_C1_F2.1262938740.info

So - if it's the tar image that you want to explore, you can have another look at my previous post where I suggest that you read up on using tar to read tapes. I have personally never tried it, but it's the only way that I think might work. The rest of us trust the NetBackup catalog and know that what we see in BAR (read from the image catalog file under ..db/images/<client>/...)  corresponds with the actual tar image on disk or on tape.
