At present, images are given a unique name (serial number?) at upload time. The unique name doesn’t have any meaning and isn’t memorable. It’d be nice to be able to specify a custom name for an uploaded image (and to rename a previously uploaded image), especially if it’s something you use often (e.g. a logo). That way you wouldn’t need to go look up the URL every time.
Great idea! Will bring “clean” URLs to some.pics soon!
