Here’s a list of sources. These are the webpages that I get most of my pictures from. Sometimes, when I edit a picture (like cropping it for size constraints) I have to remove the original tag on the image. So, if you’re ever wondering where I get my pictures from, it’s from one of the links below. Also, some of these pictures I’ve had saved on my computer for years, and they don’t have tags on them so I don’t know where I got the original image.
PS: I’ll be gradually updating this post, so there’s more links to come.
