I want multiple values for one custom field.
The value should change if a vistor clicks on a link on my blog.
I have a custom field named "picture".
This custom field should contain 2 different values.
One Value should be "www.example.com/picture1.jpg" the other value should be "www.example.com/picture2.jpg".
If someone clicks on a link "Picture 1" or "Picture 2" the value of the custom field should change to the specified value.
Please help! I am begging you please, please help!
