How can I "attach" a picture from "Pictures" to my Yahoo Emails?

How do I attach more than one picture at a time on my yahoo account?

• I have a mac and was always able to upload multiple pictures at once on my old yahoo account. Now, I have to attach one at a time and send many emails, rather than just putting them all on one. I did an online chat with a "help" person last night for an hour and a half and they told me I could do it, but they didn't know how. HELP!!!

• Answer:

  It is easy hold down the Ctrl key and click each picture you want, selected pictures will turn blue. When finished click open. You can send up to 50 pictures at a time. Be sure all pictures are loaded before you click send or it could freeze your computer. To send all the pictures in a folder right click on a picture then click Select All, they will all turn blue, click open.
