or to be more precise 1024 kilobytes (kb) = 1 megabyte (mg)

So if you're going to be directly uploading your photos to GardenWeb's site then they have to be relatively small, or if you upload your photos to a 3rd party site like a Flikr account, Photobucket, Etc. then your photos can be as big as you want, you'll just have to directly embed the link to them :)
