neocities tips/advice:
if you update your site and the changes aren't showing, go to your browser's history and clear the cache; when you refresh your site the changes should show!
what is directlinking/hotlinking? this refers to when you see an image on someone else's site, right click, select "copy image address", and use that as the src for the image on your site.
     why is this discouraged? doing this ends up using bandwidth from the site you took the image from, which can make it take longer to load. as a general rule of thumb, you should download the image and upload it to a neocities folder or other image sharing site like catbox.moe or imgur, then use the url from that as your image src.
remember to cite artists for their work! even if an image is "free to use", it is still polite to give credit. the easiest way to do this is to link the artist's site/social media to the image so that when someone clicks it, they are taken to that person's site.
