Hi Almost in all web sites in internet there is a box at left or right top corner of the web site which show some pictures and show them some times and repeat it . these pictures maybe gif animation. And these pictures have propaganda application (advertisement application, commercial application).
I use of AdRotator . but it is not what I wants.
Because the AdRotator show only one picture when the page be loaded. I want it show all my pictures every seconds. (VS2010 – C#). HOW CAN I DO IT?
Thanks very much
