I don't think it's a goal of OpenSim to serve texture assets to web browsers, nor should it be. Such a move would open doors to texture piracy and reduce any incentives for content creators to distribute their content on any OpenSim based platform. Grid operators who would want to serve their texture assets as jpeg files and make them available to web browsers could write their own conversion programs to do so. Personally I would not upload any of my textures to any service that distributes them as jpeg over http unless they were creative commons textures.
