You can divide the [random] to let it fit the interval that you want.That works if all your pictures are the same size (or somewhat) and are all .gif or .jpgYou can also put all the picture in a folder, do a listfile a first time in order to know how many pictures are there (only put pictures in this folder).This maximum value is equivalent to the last [index] of the list.Then pick a value at random, redo a listfile and when the [index] equals your value, show the picture:
Or prepare a database with the name of the pictures, a field for the index, pick at random and lookup the name according to this index. ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
