now more commonly called 'profile pictures', avatars or icons are square images people would use and upload as their user profile picture on websites and social medias.

most would probably group these in with what i've called 'ads', but i'm splitting them up. there are of course baads that are banners but there's a difference to me between banners that were made by fans to decorate the top of their page and actual advertisements made by companies or fans parodying ads. banners or headers are longer image used to usually decorate the top of a page and some socials still have banners you can customise like tumblr, x and bluesky.

dividers, sometimes called banners, are long images that are used to divide and seperate paragraphs, headers, images, etc.

pixmic is a website that lets you make collages out of various images, from images you can upload to the site or images others have uploaded to the site as 'stickers'. sadly there is group of picmix users that make collages using ai generated images, however there is another side of picmix users who are are making silly collages of their favourite fictional husbands and anti-ai collages. picmixes are typically square but you can make them in other rectangluar shapes.

mini-pixels are very small pixel art images that can be used as favicons if they're square. favicons are the litle icons that appear next to a websites name on your website browser tab above the url bar.

pixels are any pixel art images with transparent backgrounds so they're able to be easily used as deco.

stamps began on deviantart, they're typically landscape around 99px by 55px images, called stamps because they have a postage stamp border. however stamps can have various borders, and if an image is portrait or circular and still has the postage stamp border it's still considered a stamp.

stickers are photos or scans of real stickers or sticker sheets that have been edited to have transparent backgrounds

typically 350px x 19px with text on the right side, userbars were commonly used as users signatures on forum posts.

userboxes are long landscape images that had a picture box on the left and a text box on the right. the text usually says "this user is" followed by a description that matches the image on the left.
