These are photos I've collected over the years and made into transparent pngs using Photoshop.
You can use my PNGs in your site or artwork. It would be cool if you linked back to this page so other people can find these, but that isn't required. It would also be cool if you showed me (here is my guestbook and Neocities profile) because it would be super cool to see if folks use these and what they use them for, but that's also not a hardline requirement.
To use these images, save the full size image to your computer, scale it down using EZGIF or a software of your choice, make any other edits you want, and upload to your site. You want to scale the image before upload, rather than using HTML to manipulate the image's size, because browsers will load full images before scaling them down with HTML. So, using large images could slow down your website.
