Today the image viewer / gallery I had been using on #Android for ~4 years, suddenly threw a "Trial expired" in my face. Looks like the developer decided, to completely drop the "light" version, and force everyone to pay.
Long story short, I've found a better image gallery called "Aves". Much praise to the developer Thibault Deckers and all contributors. Check it out: https://github.com/deckerst/aves
