For photos that are, you know, mildly interesting

No memes. This includes references in titles of your post (e.g. "banana for scale," "potato quality").

Related posts must be in the comments of the original. Posts that acknowledge, "one-up," or relate specifically to another post are not allowed (e.g. "I see your X and raise you Y")

Do not post something that has been submitted to reddit before, even if you were the one who posted it.

Exception: If a post is deleted or removed from /r/mildlyinteresting for breaking the rules less than one hour after being submitted or receives less than 100 upvotes, we allow the submitter to resubmit a fixed version of the post. Posts deleted or removed from other subreddits are not exempt from rule 3.

a. All submissions must be original and non-animated photographs. No gifs, videos, or web sites.

b. All submissions must be original content. If you didn't take the picture, don't post it.

c. Software glitches/errors, overlaid text, arrows, scribbles, and other substantive edits are not allowed, although you may censor personal information per Reddit-wide rules.

d. Albums are not allowed, but side by side photographs (within the same image) are okay if they adhere to the rest of the rules.

No screenshots. We define a screenshot as a screen grab. This means no images of screens, pictures of screens taken with a different device, images that have been partially or fully generated by a computer, or pictures of printed out screenshots. Try /r/screenshots!.

a. Titles must not contain jokes, backstory, or other fluff. That information belongs in a follow-up comment.

b. Titles must exactly describe the content. It should act as a "spoiler" for the image. Specify what your picture shows; do not simply say “I saw this” or something similar. If your title leaves people surprised at the content within, it breaks the rule!

c. Titles must not contain emoticons, emojis, or special characters unless they are absolutely necessary in describing the image.
