Yahoo! tends to block images in signatures after a while, but you can copy an image that's already online by right-clicking it in a browser and selecting "Copy image," then pasting it into the signature box (press Ctrl-V in Windows or Cmd-V on a Mac).

You'll see two "A" buttons above the signature box when editing on a computer. The first button changes the foreground text color (the color of the letters) and the second changes the background of the text.

There's an indent button above the signature box--it's the one that has several lines with an arrow pointing to the right. You can use that to indent further, or use the align-left icon (the horizontal lines that are all flushed to the left) to realign the text.
