Yes, instead of clicking on each image to go to the image page, there is a simpler and time saving way to get the images you want in your cart and ready for downloading.
When you see the image thumbnails in search results, under each thumbnail there is a dropdown arrow (▼) and a plus sign (+).
Click on the dropdown arrow and choose the size you want, then click on the plus sign (+) and your image will fly to the right of the screen, which means it’s gone to your cart. If you missed the flying image, don’t worry, as long as you click on the plus sign (+) the image should be in your cart. To check, move your cursor over your shopping cart (top right of any page) and the images in your cart will be shown.
