How many photos will fit onto one DVD or USB?

We are able to fit approximately 500 photos onto one DVD. We can only provide an estimate because image file sizes depend on the image details as images with more details will result in a larger file size. There is no size limit on USB copies. In most cases, your photos will be transferred to a single USB, but if it exceeds our USB storage capacity, you will receive additional USBs at no additional charge.
