It is best to know the pixel width (side to side measurement) of the image you are using. This will help the table to fit tightly around the image and caption.
If you are using a PC, to find the image width, right click the image and view its properties. On a Mac, click and hold the pointer down on an image until the option "open image in new window" appears. The width and height of the image will appear in the title bar of your browser. Either way, the pixel width of an image is listed first (as in: 180 x 120).
Or, open the image in an image viewer or graphics program to find the width.
IF the image is TOO LARGE in its original size and will take up too much of your dynasty page, and you would like to resize the image to a width smaller than its original size, type the new width in the box on the form.
NOTE: It is always better to resize a picture to a size smaller than the original than to enlarge it. Enlarging gifs or jpegs can cause them to look distorted. The best choice is to find images that do not need resizing.
