A good image size is minumim 1500 pixels height or width([[media:Diego_Suarez_150.jpg|example of an 1500x1125 image]]). Many digital cameras produce images which often have an aspect ratio of with a 4:3aspect ratio. All modern cameras produce larger images larger than 1500 pixels in width or height.  If resizing a larger image which has an 4:3 aspect ratio down to 1500 pixels width, it becomes 1125 pixels in height. Or in case of a taller than wide image (i.e. portrait format) the resulting image size will be 1125 width and 1500 pixels height. However, different many cameras product offer several different aspect ratios ratio settings and image sizes size options that are usually much larger than 1500x1125 pixels ([[media:Diego_Suarez_150.jpg|example of an 1500x1125 image]]).  A good graphics application to scale images down with is [http://www.gimp.org The Gimp] It is free to download and install on all operating systems. If however you wish to avoid using a graphic application, uploading images in their original size as they come straight from the camera is fine too, but depending on your internet connection speed and the size and number of images, the transfer may take a long time.
