Where can I find high resolution images online?

Many places, and quite easily. Especially for images of artworks created before 1924 (i.e. digital reproductions that are in the public domain). Please click here for CAA's *wonderful* guide to fair use practices for images.

1. Websites of Museums, Libraries, and Archives

Institutions are formally digitizing their permanent collections.

Click here for a complete list maintained by the College Art Association (CAA).

2. Wikimedia Commons

TIP: search for art and add the term "Google" to filter out the super high res JPGs from the Google Art Project, which have been archived on Wikimedia.

3. Google Image Search

TIP: click "Search tools" then: (a) filter for "Large" size images and (b) "Show sizes". The first image has high resolution, 5872 x 4008. Try to find images whose resolution dimensions are both > 2000.

How do I connect my iPad/iPhone to a projector?

You can project your slideshows physically with an adapter (a.k.a. "dongle) or wirelessly with AppleTV.


1. Wire-full: Dongle

You'll need to answer 2 questions before purchasing a dongle:

• Do you have the "older generation" device (iPad 3 or iPhone 4 and prior) with the wider socket on the bottom, or the newer style narrow lightning socket (iPad air and iPhone 5/6)? 
• Do you have a state-of-the-art HDMI high-definition projector, or a standard VGA projector? 

Dongle adapters can be purchased on apple.com or amazon.com


2. Wire-less: AppleTV

Thanks to Apple's proprietary "AirPlay", you can broadcast your slideshows wirelessly with an AppleTV. Click here/forward this URL to your tech support team for installation assistance. To connect your device to AppleTV, drag your finger upward from the bottom edge to the screen's midpoint. Tap Airplay, select Apple TV, and switch on "Mirroring."

Advancing Slides in Presentation Mode

There are 2 ways to advance slides when you are in slideshow view mode. 

1. You may single tap anywhere on the screen to reveal forward and back arrows in the footer. Tap these arrows to move forward or back in your presentation.
2. Swipe your finger from outside of the viewing screen to roughly the center of the viewing screen. IMPORTANT: You must begin this motion from the outside extent of the viewing screen to avoid panning the image itself.
