@Queryfox,
first, learn better English. Seriously dude, my own English is broken but still more easy to read then your abbreviations...
to the point: Taking a picture during date might be cute or creepy, according to the situation. And by situation I mean personality. If you are one of that douches who drink beer on open street, wear baseball hat backwards and play cool (which resembles your writing) the yes, it was creepy because you wanted to play cool with your catch so openly.
If you are just normal guy who was proud to be with beautiful girl and wanted to show friends I don's see much harm.
There is no reasonable answer to this. Nobody can tell you how to proceed given so little info. The best thing you can do is to be honest to yourself - it is just a catch for you or are you serious with her. According to that take action. I think you'll best know what to do.
