A good image is minumim 1500 pixels height or width. Many digital cameras produce images in different sizes but and which often have an aspect ratio of 4:3. Almost all modern cameras produce images larger than 1500 pixels in width or height. If scaling an wider than tall image (i.e. landscape format) and which has a an 4:3 aspect ratio down from some larger size and down to 1500 pixels width, it should become 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 cameras product many different aspect rations and image sizes, and which are usually much larger than 1500x1125 pixels.

To avoid using a graphic application, uploading images in the original size how they come out straight from the camera is Ok too, but depending on your internet connection speed and the size of the images, they may take longer to transfer.
