Above your post (from the message), does it say something like below:

Checking for a solaris2 image
|........|
No solaris2 image has been found in
/cdrom/cdrom0/Solaris_10/Product
Then followed by your message?
It may be solaris2, solaris3 or solaris4... what this means is that it's asking for next CD (solaris2 = Solaris installation CD 2, solaris3 = Solaris installation CD 3, etc...).
Put your solaris 2 (or requested) CD in the CD-Rom drive and type
/cdrom/cdrom0
and hit Enter. Then it should continue the installation. It may say that it can't find an image but if you insert the right CD, just give it a few moment to recognize the CD and type that and hit enter. It should go through.
