Supporting information for John Doty's answer here it is important to remember that Galileo was designed in the 80s, where most camera's still used electron tube imagers involving vacuum, high power heaters and glass. The main Galileo solid state imager weighed 29.7kg and was single colour, with colour images requiring taking multiple images through different filters and combining them after reception, which is a problem if the craft moves appreciable between shots.

This means that fitting a camera into the planned descent probe was not going to be easy, and the best that was achieved was the Net Flux Radiometer, which was effectively a two pixel camera (and weighed 3kg at that).

Galileo itself was not designed for atmospheric entry, with the decision to enter jupiters atmosphere being specifically destroy it rather than because it had notable scientific merit. As such the already limited radio link capability was further constrained by the fact that it could not keep the low gain antenna facing towards earth was drag started to build up - the actual 'loss of signal' event during the entry was when it ran out of control authority to keep antenna pointing rather than heat or drag related.

So it was a craft not designed for entry, with a failed radio link that could not usefully downlink images anywhere close to real time, with a camera that could not rapidly take images anyway and where loss of signal happened well before approaching anything particularly interesting to take images of.
