We got a new client over here recently with Yahoo Hosting. It was kinda a PITA figuring out the WYSIWYG so I thought I would post it here for later reference for myself, the team, and those of you who stumble across the blog with Yahoo keywords!

• Login to your acocunt with your previosusly assigned login info at https://login.yahoo.com/config/login?.src=fpctx&.done=http://www.yahoo.com
• On the right, under yours/the client’s name, click on “Mail”
• On the left under the apple icon, click the link that is the domian name you are working in’ under the Mail Accounts heading
• On the top right click Manage my services
• On the left click Web Hosting control panel
• Click the Manage Tab
• Click file manager – this takes you into the main web directory. Make
  sure you don’t delete anything! In order to upload a file, click
  “upload files” on the right
• If you need to upload anything to the images folder, you have to click
  the folder name, and THEN click upload files on the right.
