You can upload all of your photos as .jpg files up to 50MB in size each. Your images should be in the sRGB color space.
Files should be at least 3000 pixels on the longest side to ensure they take up the maximum viewing space in the gallery, but higher resolution files are not necessary. If you are selling digital downloads or sending these photos to print, you may wish to upload higher resolution files.
Be sure your file names do not have special characters in them; we also recommend using filenames without spaces, if possible.
