If you have permission to download images found online and to use them in the exhibit, then please download images with the following minimum specs:
Note: you can control these elements when you are the one scanning images. If you find images from online sources, focus on digital collections that allow downloading as they will often offer file downloads at the required image resolution level.
A surrogate image at its most basic is a high quality copy of the original. If you find your image from an open access digital image collection, that digital image that you're viewing on your computer screen is a surrogate for the original physical item. If you find an image in a physical book or other physical item, you may need to scan the original and print a copy to use in the exhibit; that printed copy is a surrogate.
Why?
A surrogate is particularly helpful when the original is rare and/or fragile, as it reduces wear and tear on the original object while also making it available to a much larger audience.
In the case of this project, you may need a surrogate either because your original object is held at other institutions and you are using a version you found online, the original object is too big to fit in the display case, or the display case doesn't have the safety features some special collections require to display the original object.
