i see some people post and under their name they have a picture of themselves, how do i put a picture on mine?
and then when you click their picture they fill in their interests etc, how can i do this?
You need to use a tool such as Windows Picture Manager, Irfanvew, Photoshop, or other photo manipulation tool to reduce the picture to a maximum size of 120 x 120 pixels.
It is best to use a picture that is just a head shot or find an image that is already reduced. You can also crop an existing picture and reduce that. If you are cropping and reducing an existing picture try to use the best quality of picture you can. Images lose their quality as you reduce them.
Here is a link to Irfanview. It is one, free, product I use to reduce photos.
