Thanks Pieter, for explaining things that tbh never caused me any problems.
Ad 1: Usually I click on a picture in my files when uploading, so I know what I am doing. I have never so far uploaded a different picture than intended.
Ad 2: First I prefer searching via IMO number but when it has to be I would like to type the full name, not having to read a great number of different queens as per your example, but I can imagine people will like it, especially those who do not know the IMO number of the Fliegerkosmonaut der DDR Siegmund Jahn or the numbers of several SCI tankers named after military heroes.
