I have tested it on 6 different browsers
Chrome: ~5 seconds then crash
Safari: ~5 seconds
Perfect Browser: I was able to navigate to a few links (residental/leisure), but it inevitably crashed in maybe ~45 seconds
Icab: almost instant crash
Browser inside of the Goodplayer app: I was (surprisingly) able to get around for almost 2 minutes, but when it crashed, it crashed my whole device, not just the app.
Dual Browser: This one did not crash. However, it is a non-conventional browser, it is split down the middle so you can put a different website on each side, I don't think this is a viable solution for your case.
My conclusion is that it is, without a doubt, a memory related crash. Being jailbroken, I can see my available RAM at any moment, and after every crash it is under 100 (60-80mb), which in my experience, is the bare minimum apple with allow for the iPad 3 before force-closing apps. (It is usually just under 800mb without any apps running)
I can see that the transition between pictures causes obvious lag.
