Not sure if this is the right place, or if it’s been done before but:
I’ve been doing this for a while now and figured I’d add this tip in case other people find it helpful.
Instead of uploading images to lemmy world and taking up disk space, when I have an image I want to add, I right click and copy link.
Then paste the link inside () after writing ![] like so:
![](www.google.com/image.jpg)
It becomes second nature pretty quickly.
EDIT: ok so to avoid hotlinking, upload/copy the image to catbox, and then use the technique described above.
Does this not work for you??
