Use tags
Tags – use tags (the underlined words at each photo). An example: Click on the tag of „Nymphalidae“ and all brushfoots (Nymphalidae) will display. The tag „copulation“ shows you all the photos of mating. The label „Mauritius“ or „Hegy Farok“ show you photos of these places. And so on.
I chose some interesting tags and put them on the title page (you can find it under a link „Interesting tags“).
