Default Dropping a Probe w/Camera into a Jovian Planet

If you were going to build a probe that was similar to the one dropped into Jupiter-this time, with a camera-how would you outfit the probe so that the camera could take decent pictures? Is such a thing possible?

I ask this because I've always wondered what the skies would look like on Jovian worlds. I also ask in part because, if I understand correctly, the Hyugens probe will be taking snapshots as it descends to the surface of Titan.

Could such a probe, with modifications, be dropped into a planet like Jupiter or Saturn, with the ability to send back decent pictures? Has this ever been discussed by scientists?

Probably a balloon that would inflate after the probe entered the atmosphere would be the most practical. The probe could drift around for a time, at various altitudes sending back pictures if possible, but certainly other data as well. This may even work with Venus, if the upper atmosphere is cool enough, I don’t know what to expect for temps there, but certainly far too hot and too much pressure at the surface. And on Jupiter or Saturn there is no assessable surface at all as far as I know.

Both Soviet Vega probes released balloons to the atmosphere of Venus on their way to Comet Halley.

The proposed American Venus lander is supposed to land on the surface, grab a sample, send it up with a balloon from the surface and study it while hovering high up in the cooler atmosphere. That suggests even the atmosphere at the Venusian surface is not too hot or has too high pressure for a balloon to work during a limited time (or the ascend phase would be impossible).
