We have provided high and low resolution versions for most graphics. Usually the high resolution images are used for print design and take more time to download, while the low resolution images can be used for computer graphics such as web, power-point, etc. and take less time to download. If you are downloading high resolution images, it is best to use a high speed internet connection to avoid extremely long download times. However, please be prepared for long download times regardless of internet speed. These high quality image files are quite large to provide you with the maximum quality for your design.
There is only one resolution available for vector images because these types of files can be scaled to any resolution without losing quality while maintaining a relatively small file size. Also, some graphics only provide high res files due to the small file size.
