The 88x31 GIF Collection is a nostalgic nod to an era of internet graphics, particularly tied to sites like GeoCities. The size 88x31 became a standard due to its widespread use in those early web environments. User commentary discusses the uniqueness of this size, the technical aspects like frame loading times and browser capabilities, and the possible NSFW content within the collection. The juxtaposition of these vintage GIFs and modern screen resolutions (like 4K) highlights a contrast between past and present viewing experiences.
