Generally you need an active support contract to obtain (and legally upgrade) an IOS. Do you have such?

If not, Cisco will, upon contacting them, allow for some upgrades to address serious security flaws. Also, some devices, have (or did have) special licensing for lifetime upgrades (although you may need to document your the original buyer). I don't know if either applies to your device and its IOS.

First, you need determine which IOS is suitable for this router - try cisco feature navigator.

Second - 871 is end-of-sale and end-of-support. Therefore, you will not be able to download the desired image on the Cisco website. But it can be found on the internet...

What @Joseph W. Doherty said is correct.  
You need a valid Service Contract to download the IOS.  Unfortunately, the 870-series router is already end-of-support.  This means all relevant firmware files have been removed from the Cisco download pages. 

If you have the exact filename of the file you are looking for, Google will be your friend.

Check for a valid service contract from where you bought it. Or call directly to Cisco TAC number which you can find online.
