Cisco 1721 IOS upgrade

I have a Cisco 1721 with an IOS of 12.3 . I upgraded the IOS with the image c1700-k9o3sy7-mz.123-15 to 12.3 but the system crashed on startup with the following error. I had to use xmodem to reload the old IOS. How can I resolve the error below

system operation may be compromised.

The difference between Memory required and Memory available is the additional
memory you need to run the router. Alternately, use a smaller image; this
may cause the memory requirement to decrease, and may allow you to at least
use the router with reduced functionality until you get more memory.

I see the message INSUFFICIENT MEMORY TO LOAD IMAGE!

Have you considered the possibility that you loaded an IOS that is too big for your router to handle? It looks like you only have 32MB RAM when your IOS image requires 42ish.
