I really like it. Tech comminities & some others are very bouyant & interesting but niche communities really struggle. Even direct replacements of big subreddits struggle. Hopefully this improves.
One tip from my own experience. I use Voyager & blocked a load of US politics keywords.
And another, I subscribed to as many interesting Lemmy communities as i could then browse Home feed in the main & occasionally All to see if any other interesting communities crop up that could be worth joining.
Welcome & enjoy.
For images, on Android you could use Imagepipe.
Once you’ve set it up, simply “share” the image to Imagepipe, it does its thing then automatically passes it on to whatever app you want - for example a messaging app for you to send on to others (it stores a copy of the image minus its metadata in an Imagepipe folder in your gallery for ease of access should you need it again).
For video, from memory I think mp3tag for Windows/Mac can remove metadata from some video formats
