image0uri contains a string that is the Universal Resource Identifier for
the image file that is loaded and displayed in each section of the

The next two lines of code declare two more variables:
var currImage:Number = 0;
var totalImages:Number = 4;
The first variable,
currImage
is being displayed in the
, stores the total number of images that are available to be
totalImages
displayed. By storing this last number in a variable, you make it easier to
change the number if you want to add more images to the slide show later.

The next line of code sets the text of the title text box to the text in the
variable whose name corresponds to the current image number.
menu_mc.title_txt.text = this["image"+currImage+"title"];
This code uses dot syntax to set the text property of the title_txt text box in
the movie clip instance to the value of a variable. In this case the
menu_mc
variable name is constructed from the word image plus the value of the
variable, plus the word title. The variable name becomes
currImage
or one of the other similar variable names, depending on the
image0title
number contained in the
Flash that the variable was declared inside this same script.
The following line of code is similar to the previous one:
menu_mc.description_txt.text =
this["image"+currImage+"desc"];
This line of code sets the text of the description text box in the
movie clip instance to the text in the
current image number.
The following lines of code set up a
