That’s true. 
The Uploaded Photos 2020 topic is a good place to burn through some Likes. And you get a Badge for using all 50 in a day (I don’t know if that’s actually ‘use your max Likes in a day’, as then it could be 75 or 100?), and then doing that 5 and 20 times.
Posting photos is a good way to receive a few too, but it may be a bit extreme if you’re doing it just for the Badges. 
And the #your-photos topics are ineligible for the Nice/Good/Great Reply Badges anyway as it’s a semi-private category.
Edit: Uploaded Pictures Thread Part 2 is a very friendly topic that gets a lot of love thrown around, and you don’t need to have posted a photo yourself to give someone else a little confidence boost.
