I thought this was rather interesting:

Rich posted it in the TS Bonnie thread a few days back. Funny how those clouds stream off the tips of the islands in the Bahamas.
 
A lot of those islands in the Bahamas have a unique chevron shape to them. I wonder if that has anything to do with it? Awhile back I heard the chevron shape of the islands had something to do with a gigantic tsunami that crossed the Atlantic many moons ago. It was on Nat Geo or Discovery IIRC.
 
Good day all,

The Bahamas create what is called "atoll" clouds, and in light wind conditions, a thunderstorm forms right OVER the island (from sea breezes and diurnal heating of the land).

If there is a strong wind (easterly trade winds in the Bahamas case), the clouds that form over the land are quickly pushed away from the island, and a narrow cloud "line" forms, instead of an atoll cloud / thunderstorm.

As for the other pictures, the clouds are not convective, but stratiform, such as in the Pacific Ocean, especially off California (for example). In those cases, eddies and / or gravity wave patterns can be noted with island "wakes".
