(Sorry if this is a silly question, but)
So I see a lot of awesome pixel art on sites like TIGSource, pixeljoint and deviantART as well as the personal websites of various artists, and it seems like it might be nice to be able to study the pixel art up close (when I'm not so busy...). But it'll probably be inconvenient to have to study them within the browser because zooming in might not work as one would want it to, because one might have difficulty keeping track of various links to the pages with pixel art, and because one day one might find that the website with the pixel art you want to study has shut down.
So I was wondering if it's generally okay to download the images as long as they're only for personal use? Does it depend on the site the image is from? It sounds like a hassle to have to root through the privacy policies, terms of service and FAQs of each website, and even then it might be unclear what exactly one is allowed to with the images. Thoughts?EDIT:
For example, it sounds like you can't download images from pixeljoint:
