Need assistance to download 2821 ISR router IOS image

[vikram4]

We plan to upgrade IOS image in cisco 2821 ISR router.

The image running currently is 12.4(24)T4 and this image was released in 2011 (or maybe earlier). So my guess is newer image might have been released for this model as Cisco site shows that End-of-Support Date for this model is: 2016-11-01.

However iam unable to find IOS image download page for this model in cisco site. Is there any archived cisco link for downloading image?

Cisco has removed all relevant information, including IOS files, after End-of-Support date has been reached. 

Your best option is to enter the filename into a search engine and see where it takes you.
