hey gang, in case this helps:

here is js file i am using


///////////////////////////////////////////////////////////////////
/*Site Logo Script (Geocities Watermark)
Dynamic Drive (www.dynamicdrive.com)
For full source code, installation instructions,

///////////////////////////////////////////////////////////////////

//edit the below 5 steps

// 1) substitute 116 and 42 with the width and height of your logo image, respectively
var logowidth=50
var logoheight=50
var logoimage=new Image(logowidth,logoheight)

// 2) change the image path to reflect the path of your logo image
logoimage.src="http://dls.diamondlot.com/UserFiles/dog2.gif"

// 3) Change url below to the target URL of the logo
var logolink="http://dynamicdrive.com"

// 4) change the alttext variable to reflect the text used for the "alt" attribute of the image tag
var alttext="Dynamic Drive"

// 5) Finally, below variable determines the duration the logo should be visible after loading, in seconds. If you'd like the logo to appear for 20 seconds, for example, enter 20. Entering a value of 0 causes the logo to be perpectually visible.
var visibleduration=12

// Optional parameters
var Hoffset=0 //Enter logo's offset from left edge of window (edit only if you don't like the default offset)
var Voffset=0 //Enter logo's offset from top edge of window (edit only if you don't like the default offset)

i am in a bind and need to have a form of javascript place an image in a certain spot as the html edit area i have access to is for the header, i want this logo to appear in the content section below the header column


if there any other easier ways to do this, i would greatly appreciate it.

i cant use basic <img src> locations as the area i want the logo to appear is out side of our html div's

Can you make this logo bottom center of page.

i cant do it with basic <img src> tags due to the location i want it

Of course you can, just make it absolutely positioned, example:


<img src="logo.gif" style="position: absolute; left: 600px; top: 500px;" alt="logo">

Place it outside of everything else on the page. Like make it the last thing before the closing </body> tag.

We have modified this script to accept some html but how do you get the script to always center on page?



varLogoHTML = '<table width="940" border="0" cellpadding="0" cellspacing="0" >';
varLogoHTML = varLogoHTML + '<tr>';
varLogoHTML = varLogoHTML + '<td align="right" valign="bottom"><div align="center"><font face="Arial" size="3" color="#0000FF">call Phone</font></div></td>';
varLogoHTML = varLogoHTML + '<td align="right" valign="bottom"><div align="center">or <a href="">Email Us</a></div></td>';
varLogoHTML = varLogoHTML + '<td align="right></a></td>';
varLogoHTML = varLogoHTML + '</tr>';
varLogoHTML = varLogoHTML + '</table>';
