You must provide at least 1 image along with your project, and you can provide as many as 3 images. The images must be JPEG (or JPG) format. This is the standard image format used by most digital cameras.
Once the images are uploaded we will resize them to 440 pixels for use in our layout. For most digital cameras you can take pictures at a "low" or "medium" resolution for this use. Using higher resolution will produce a much larger file, which will take much longer to upload. Because the image will be shrunk ultimately, the extra resolution offers no advantage.
If needed, crop(To crop is to select the important part of the image and delete everything else) the image before uploading so your project is shown to best advantage. If you supply an image with too much "space" around the actual item you are showing (i.e. shot from too far away), the item may be hard to see. You may already have the software to do this, because it is often included with digital cameras. Or there are free programs, like Google's Picasa, that can do this for you.
Below are two examples of the Lincoln Memorial, both having started from the same original image. One is reduced to 440 pixels wide with no other modifications. The second version was cropped first, then reduced. The cropped image gives you much more detail.
