(I am very novice at web programming) Is there a simple change I can make to this code in order to not have a repeat picture till all the pictures were displayed?</p> <pre><code>var delay=7000 //set delay in miliseconds var curindex=0 var randomimages=new Array() randomimages[0]="content/indsidebar1(2).jpg" randomimages[1]="content/indsidebar2.jpg" randomimages[2]="content/indsidebar3(3).jpg" randomimages[3]="content/indsidebar6a.jpg" randomimages[4]="content/indsidebar5.jpg" randomimages[5]="content/indsidebar6.jpg" randomimages[6]="content/indsidebar7.jpg" randomimages[7]="content/indsidebar8.jpg" randomimages[8]="content/indsidebar9.jpg" randomimages[9]="content/indsidebar10.JPG" randomimages[10]="content/commersidebar1.JPG" randomimages[11]="content/commersidebar2.JPG" randomimages[12]="content/commersidebar4.JPG" randomimages[13]="content/commersidebar5.JPG" randomimages[14]="content/commersidebar6.JPG" randomimages[15]="content/commersidebar7.JPG" randomimages[16]="content/ressidebar1.JPG" randomimages[17]="content/ressidebar2.JPG" randomimages[18]="content/ressidebar3.JPG" randomimages[19]="content/ressidebar4.JPG" randomimages[20]="content/communsidebar1.JPG" randomimages[21]="content/communsidebar3.JPG" randomimages[22]="content/communsidebar4.JPG" randomimages[23]="content/communsidebar5.JPG" randomimages[24]="content/communsidebar6.JPG" randomimages[25]="content/communsidebar7.JPG" randomimages[26]="content/communsidebar8.JPG" randomimages[27]="content/communsidebar10.JPG" randomimages[28]="content/undersidebar1.jpg" randomimages[29]="content/undersidebar2(1).jpg" randomimages[30]="content/undersidebar3.jpg" randomimages[31]="content/undersidebar4.jpg" randomimages[32]="content/servicesidebar1.jpg" randomimages[33]="content/servicesidebar2.jpg" randomimages[34]="content/servicesidebar6.jpg" randomimages[35]="content/servicesidebar4.JPG" randomimages[36]="content/servicesidebar5.JPG" var preload=new Array() for (n=0;n&lt;randomimages.length;n++) { preload[n]=new Image() preload[n].src=randomimages[n] } document.write('&lt;img name="defaultimage" src="'+ randomimages[Math.floor(Math.random()*(randomimages.length))]+'"&gt;') function rotateimage() { if (curindex==(tempindex=Math.floor(Math.random()*(randomimages.length)))) curindex=curindex==0? 1 : curindex-1 else curindex=tempindex document.images.defaultimage.src=randomimages[curindex] } setInterval("rotateimage()",delay) </code></pre>

    1. COThis won't answer your question, but it will help you write better code. Remove `language="javascript"`, as that's deprecated. Replace `new Array()` with `[]`, which is the better way of instantiating an array. And don't use `document.write`; instead, insert the image in the DOM.

    2. COYou'll probably want to look into the [Fisher-Yates Shuffle](http://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle) for randomizing the order of the images.

    3. CO@DerekHenderson Do you have a reference for `[]` being a better way of instantiating an array?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
