  • How to add photos only when someone click mouse in the box

    As in the thread.

    I want my picture that someone will see only when click a box on my site.

    You can create objects on the page, and then set the States, for example, insert a rectangle and set reports with the mouse to the bottom of the State, so that once the user clicks the rectangle, image used for the mouse to the bottom of the State will be displayed on the page.

    If this isn't what you are looking for, please let me know.

    I use Mac OS 10.6.8.

    I contacted my ISP (Optimum) and they said tell Firefox to my computer to make the sound. They say that they have no control over it.
    I tried to reduce the volume of alerts in my system prefs, but it has not affected the volume of FF.

    Thank you!!! The 'sound' button off in their preferences. Fixed. (It was so freakin ' fort!)

    I, in turn, chatted with Service to customer of Optimum and tells them that they must tell their supervisor to better educate their own service to the customer, instead of passing the ball. We'll see.
