Now you can customise your Yahoo profile pic. Simply choose your relevant characteristics above.

When you're happy with the result, press 'Alt + Print Screen' (located towards top right of your keyboard). Then open Paint and select File/ New.
Select Image/ Attributes and change the size to 150x150 pixels.
Now select Edit/ Paste and drag the image towards the top left until the profile pic fits neatly in the square.

Then simply Save. Warning: you will need to convert the image to JPEG or GIF format as a BMP may be too large a file. This can be done in Photoshop or a similar program. Then you're ready to upload it to your profile!
