The largest majority of images on this site are standard horizontal format so I have not repeated those here. Here you will find the two minority formats; Vertical and Panoramic which will greatly help when those specific formats are desired.
I should point out the availability of cropping an image does exist in some cases. For example a horizontal image may be cropped to a more panoramic format. This will obviously remove portions of the top, bottom or both and possibly sides as well depending on the desired finished image.This will, in most cases reduce the size in which the image can be printed and larger version may no longer be available. Cropping can work with some but not all images such as horizontals to vertical or verticals to horizontal and still maintain the desired outcome. If you have any questions on cropping or the possibilities of any image simply contact me. I am always happy to help create the image you need.
