The Search-by-image feature is especially powerful for hard-to-articulate concepts if you have one photographic example. Click on the camera icon (right side of search box) and provide an image to seed the search.
Academic Search Premier is a multi-disciplinary database that provides citations and full-text for articles published in nearly 4,500 journals, including more than 3,700 peer-reviewed titles.
You need to include referenced photos into the flow of your writing, like a magazine article does.
The best way to do this is to download the image to your computer, then to upload the image into the document.
Some sites will provide specific download links, perhaps in different sizes. Use when available.
When no download links are provided, right-click the image (or on a Mac: Ctrl + click) and select Save As...
Sites such as Instagram and National Geographic block downloads or require payment, to protect the copyrights of image creators. You are referring to these images as sources in a critical and educational context, and not presenting them as your own. While not ideal, you can screenshot the images themselves, and refer to the metadata (title, composer, location, etc.) for your citation. Here's how:
Select the image in its entirety, as the creator presents it. Do not crop or alter it in any way. Professional photographers may have a watermark superimposed on the image--that is OK.
Copy and paste the URL for the image before you leave it.
For Instagram: Find the Copy Link command: On mobile, find it under the three dots upper right .... On desktop, find it under the Share button . Open a new tab and paste the link. You now have the single post view rather than your feed view.
