I want to refresh only the main image on a motion jpeg page not the whole page. Any ideas.
Thanks |

| Code: |
<!-- Code Begin -->
<IMG src="image_name.jpg" width="275" height="200" border="1" name="refresh">
<SCRIPT language="JavaScript" type="text/javascript">
<!--
var t = 120 // interval in seconds
image = "image_name.jpg" //name of the image
function Start() {
tmp = new Date();
tmp = "?"+tmp.getTime()
document.images["refresh"].src = image+tmp
setTimeout("Start()", t*1000)
}
Start();
// -->
</SCRIPT>
<!-- Code End --> |
Try this one - I use it to refresh my webcam pics. Just insert your on image address and interval time |

One of our websites uses this script to generate a random top banner image.
This is the site
http://www.crescohomes.com
Here is the script in the HEAD portion
| Code: |
<SCRIPT LANGUAGE=JavaScript><!-- Hide this script from old browsers --
var imagenumber = 7 ;
var randomnumber = Math.random() ;
var rand1 = Math.round( (imagenumber-1) * randomnumber) + 1 ;
images = new Array
images[1] = "banner1.jpg"
images[2] = "banner2.jpg"
images[3] = "banner3.jpg"
images[4] = "banner4.jpg"
images[5] = "banner5.jpg"
images[6] = "banner6.jpg"
images[7] = "banner7.jpg"
var image = images[rand1]
// -- End Hiding Here --></SCRIPT>
<SCRIPT LANGUAGE=JavaScript><!-- Hide this script from old browsers --
var imagenumber = 5 ;
var randomnumber = Math.random() ;
var rand2 = Math.round( (imagenumber-1) * randomnumber) + 1 ;
images = new Array
images[1] = "frontpic1.jpg"
images[2] = "frontpic2.jpg"
images[3] = "frontpic3.jpg"
images[4] = "frontpic4.jpg"
images[5] = "frontpic5.jpg"
var image2 = images[rand2]
// -- End Hiding Here --></SCRIPT> |
This code is the BODY portion
| Code: |
<BODY BGCOLOR="#DBDFD4" marginheight=0 topmargin=0 marginwidth=0 leftmargin=0>
<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 WIDTH=621 HEIGHT=77 align="center">
<tr>
<td><img src="topbanner.gif" width="620" height="27" align="top" alt="Top Banner"></td>
</tr>
<TR>
<TD VALIGN=top>
<P><IMG SRC="toplogo.gif" ALT="Cresco Homes" WIDTH=189 HEIGHT=77 ALIGN=top><SCRIPT LANGUAGE=JavaScript><!-- Hide this script from old browsers --
document.write('<IMG SRC="' + image + '" width=431 height=77 align=top>')
// -- End Hiding Here --></SCRIPT>
</TD>
</TR> |
Perhaps the "' + image + '" can be placed in the BODY tag for the background image. Play with it and see what happens. |

| I have no idea if it will work - Java is not a strong point for me. |

Hi, I'm new around here, so please excuse me if this had already been asked somewhere..
Is there a way, possibly using the code provided in this topic to refresh a single remotely-hosted (webcam) image with another remotely-hosted (webcam) image (different URL) on the same webpage after a few seconds delay without having to use a META refresh command to auto-load a new page, and a new image, I would also (if possible) like with a small caption above the image (which also changes with the image)?
Any and all help gratefully received. |

Digi Spy,
yes it will work. You have to make all the variable names different, including the name of the function. But don't change the names of the built-in functions: i.e. Date()
I have this on one of my webpages |
