If you are talking about images that you can bring up such as ... 'flower images'

Click on the images label when it appears then scroll down until you find the picture you like...

Left click on the image so that it appears on your screen.

Right click on the image and scroll down to copy.  Click on copy.

Go back to this section and  left click then right click... choose paste... it usually doesn't work the first time ... so repeat.  Magic!

Do you know how to copy and paste? You have to right click on the image (image found on the internet) then copy the URL address (option may read, copy image URL) then come back to akaQA and in the add new answer box, click the tree image   

then you will see this box 

 Where it says, image url you would right click into that and select paste. This will paste  the url address into the long box. Once pasted, you then click the button labeled "insert" as seen on the above image.  Once you've finished, click "post an answer".
