Code review comment for lp:~stellarium/stellarium/toastImages

Works like a charm as long as network is good.

Maybe fix following: When disabling network (tset with aircraft mode on notebook), and reenabling, re-establish connection? Not sure what happens currently, network stays disabled. What about short network interruptions - would we have to completely restart Stellarium (and break connection to telescope etc.) to re-enable? It may be acceptable to toggle DSS off/on to reconnect. Maybe give screen notice "DSS: network unavailable" or such?

Things to possibly consider:

Fix TODOs (links) in ToastMgr::init(), and host data at stellarium.org?
Explain what TOAST actually means?
We should be prepared to answer questions about installing data locally (for use at off-line observing sites! Either private PCs or data on an in-house server.) (source, legal state, bandwidth, instructions?)
A chapter in the Guide should explain all this! (Can be added after merge, though.)
