Apparently this is a subject of discourse on Twitter now, but for the record, all the art I post here is free for personal/private use!
I do really appreciate that people ask before they use my work, because many artists clearly feel differently than I do, and I think asking is the best practice for engaging with art online. Creators do have the right to determine how their work is used. "All Rights Reserved" includes the right not to have your work redistributed, even online.
But in the case of the vast majority of art I make, I have zero problem with you doing General Personal Use things with it: saving it to your phone, making it your desktop background, posting it in the groupchat, adding it to your character sheet for your friend's D&D session, printing it out and putting it on your wall. I AM glad people ask me, if only because I can feel good about myself that someone likes my work that much, but there's literally no way for me to know if someone does any of these things, and it doesn't really affect me much if they do.
If you share my work publicly, such as making it your icon on tumblr/twitter/discord, posting it to Pinterest, putting it in a forum or on a webpage, etc, you must provide credit, which is as easy as linking to my website or one of my social media pages. Basically, if there's an instance in which strangers could stumble across my work and ask, "who made this? Can I use it, too? Does this person take commissions?" they should have a method of finding me and looking that up. Some artists don't want their work shared, even with credit. But I'm pretty small-time in the online art world, and I do appreciate the exposure. (Note: some websites have "we own the rights to anything posted here" clauses in their TOS! DON'T repost art to websites like that! Usually they will ask YOU if you own the rights to the art you're posting. If it's someone else's art, you don't.)
Things that are NOT personal use and which I would like people to stop doing to my art forever: editing or tracing it, reuploading it to print-on-demand sites and trying to sell it, tracing it and then attempting to sell the traced art, making it a graphic or a logo for a company or website, basically trying to make money off of it in any way ... hopefully you understand the difference, here! (I don't have a problem with someone tracing my art for their own entertainment or for practice, but don't repost it, please.)
Unless I've specified otherwise with a piece (e.g. it's too personal, it's a commission and the commissioner doesn't want it shared widely, etc), you can download it, you can share it with credit, you can do anything else personal with it.
