We can definitely add older Operas to the blacklist if they are problematic. First we need to investigate if the issue is at the OOJS level, in which case if might be fixable, since OOJS now supports older ES3 browsers thanks to a shim.

It looks like we're only blacklisting old versions of MSIE now? I saw a user report that it completely blocked image views on an older browser and just went into crossbrowsertesting.com to test with Opera 10 (they didn't specify a browser but Opera and old IE versions are always my first guess). Indeed image clicks just die -- and the error console throws oojs errors. 

Seems to me like we either want to most likely significantly expand that blacklist to cover older, more obscure browsers that otherwise lose complete access to images, no?
