I am trying to copy a google doc from my drive into a Canvas assignment , which includes 3 images of element spectra. The words come over but not the images. How do I rectify?
You cannot copy/paste or drag/drop images into Canvas through the web interface (I am not familiar with the limitations of the mobile app). This has been a long-standing feature request and is currently on Product Radar at Paste Images into Canvas. Canvas really likes to hear from students, so I encourage you to to check that out and possibly leave feedback.
The first place to look for a solution is found in the Canvas Student Guide: How do I create a hyperlink or embed a file from Google Drive into the Rich Content Editor as a student? That may not be an option for you, but if it is, it's probably the simplest way.
If that doesn't work and your assignment requires a file upload, then you can just create a Google Doc and include your images directly in the document.
If that doesn't work because it's a text-entry submission, an essay question in a quiz, or a discussion, then look at How do I add images to my assignment submission? and How do I embed an image in a discussion reply as a student? Note that there is no uploading of an image that you want to embed directly from the Rich Content Editor's embed feature. You can give a URL, reference a previously uploaded file in Canvas, or use Flickr. The example at the bottom of the "assignment submission" page is for when the entire submission is an image.
The whole uploading your files into Canvas first, as the documentation says, is one way to accomplish this, but it's kind of a pain. Luckily, there is another way. In Google Drive, you can share your images and then use the share link as the source for the URL when embedding an image.
I attempted the last suggestion (using my Google Drive shared link for a jpeg file). Canvas only inserts a placeholder--not the jpeg image itself like inserting a Flickr image online. Canvas has a few things to learn from WordPress.
