A good image is minumim 1500 pixels height or width. Many digital cameras produce images in different sizes 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 an 4:3 aspect ratio from some larger size 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 cameras product many different aspect rations ratios and image sizes and which are usually much larger images than 1500x1125 pixels.

A good graphic graphics application to scale images with is [http://www.gimp.org The Gimp] Free It is free to download and install and works on for all operating systems.

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