How to download images when sent to you by DropBox
When you receive your link to dropbox - click to view images. To get the highest resolution - don’t right click and download. This will give you low resolution images. You will want to choose the download option on the dropbox website.
There are two ways to find the download option. Click the check box next to the folder. Then choose the 3 dots to right and select Download.
Other option - click on the folder and check the box next to each image (or all) and choose the download button on right. The button appears when you check the boxes.
