There's actually no obvious way to download an image from a Google Docs document . However, the solution that we are going to propose is not too complicated to apply either..
Download an image from a Google Docs document
It's the easiest way to do it. While we are in Google Docs, we will have to go to File > Download > Web page (.html, compressed) in this way the page will be compressed and downloaded.
Next, we will have to go to the downloads folder or where we have located the file, we will have to look for a zip file with the name of the document. We will unzip this file and inside the folder we will look for one called Images..
Now we are simply going to have to search for the folder in question and we are going to find all the images that the Google Docs document had.
Publish on the web
This would be another method, although a little more indirect. We are going to have to go to File > Share > Publish to the web from our Google Docs document..
Here we will have the possibility of publishing a link or an insertion. On the Link tab, we're going to click Publish and when it asks us if we really want to do this, we simply click OK.
We will see a pop-up window appear with a link to a website, we will copy the link. We will open the URL that we copied in a new tab and now we will be able to right click on any image and save it as we normally would.
From Google Keep
Although images cannot be downloaded directly from Google Docs, we can do so from the Google notes application, Keep. We right click on the image we want to download and choose See more actions > Save to Keep.
Now we can search in the Google Docs sidebar or we can open Keep in a separate tab. Whatever the case, in the new note we will be able to find the image, it will be a matter of right clicking to download it.
