Pictures for online dating platforms

Where do you get your pics for online dating platforms from? Not sure to what extent the issue is common, but I hardly have pictures of me taken in the last couple of years.

I travel quite a bit but alone and I normally take pictures of my surroundings, not of myself. My friends all have families and asking them to take a bunch of photos of me doesn't seem like a good use of their or my time either.

I had some pictures taken in the professional context, but won't use them since I would be easily googleable if I do.
