Find Images Fast:

Cite Source


Before using any images please check the copyright statement for each database or site. Generally, most allow the use of their material for educational, noncommercial or personal use as long as the source is acknowledged.  ArtStor, for example, allows use of its images for educational purposes such as in papers and presentations, and on password-protected course Moodle sites, but prohibits use in publicly-accessible webpages and commercial publications.

Don't forget to cite the source of any images you use in papers or presentations, just as you would cite other resources!


Certain images in ARTstor provided by the Metropolitan Museum of Art and other institutions are publication-quality images and are available free-of-charge for use in scholarly publications. These images will display an "IAP" icon beneath the thumbnail. Clicking on the icon will lead a user through steps for downloading the publication-quality image, including agreeing to a terms and conditions statement.

PowerPoint is the most commonly used presentation software and is available on all Trinity College lab & classroom computers.

It should be noted that users can choose to download ArtStor image groups as PowerPoint presentations, with a slide automatically created for each image in the group, and a title slide created using the name of the group.  

A jpg image file of 1024 x 768 pixels, at 72ppi resolution, is commonly recommended for use in PowerPoint presentations.  This is the output resolution of many projectors.

Inserting an image into a PowerPoint slide:

1  First open your presentation and select the desired slide.

2  Click on the "Insert" menu

3  Select "Picture", "From File..."

4  Navigate to where your image is located, and click on the filename.

5  Click "Insert"

6  PowerPoint will insert the image in the middle of your PowerPoint slide. If the image is too big and fills the screen, click on the page zoom button & choose a small number, enabling you to zoom out to see the entire image.
7  To scale the image without distorting it, click and hold with the left mouse button on any one of the corner "handles" & drag the handle to re-size the image smaller or bigger.

Start by Creating an Artstor account if you don't already have one. This will allow you to download images and to access Artstor while off the campus network:

1.  Go to Artstor ( while on the campus network. Click on Artstor Digital Library near the top of the page.

2.  In the Log-In area at the upper right corner, click on Register.

3.  Enter a valid email address and make a password (do not use symbols or diacritics).  Provide any other basic info requested. Click Submit.  You'll be logged into your new account and a welcome message will display.

Note: After creating an Artstor account while on the Trinity network, you will then also be able to access Artstor ( when off the Trinity network by entering your Artstor username and password. This will allow you to access course image groups while away from campus without logging into the Trinity network.  

To Access your Course Image Groups:

1.  Enter the Artstor database ( and log into your Artstor account.

2. Go up to the Browse menu and choose Groups.  At the left side of the screen, under Groups, choose Institutional.  From the Tags list below that, choose your course's name or number.  The course image groups will then appear listed to the right.  Clicking on any group will display thumbnails of all the images.  Click on an image to enlarge and view its data.  You will also see options to print or download an image and its data.  

Another option is to print or download an entire image group by going up to the Share menu.  You can choose to generate a PowerPoint presentation, or to generate a zipped folder of the images.  Once your choice is "generated," you can select Download.
