thanks in advance
td a img {
width: 100px;
height: 100px;
}
td a:hover img {
width: 200px;
height: 100px;
}
just specify the some names for the tags as you do not want this to apply to all images.
thanks for the reply
i tried as you said but it increased the sizes of the tabs not the images
please tell what wrong am i doing

So you could specify the class for the td element and add an <a> tag to get control of the hover so it becomes like:
echo '<td class="dual_size" border="1"><a href="javscript:void(0)"><img src="' . $cimage . '" /></a></td>';
then in the stylesheet you have the code I posted like above specifying the class
td.dual_size a img {
width: 170px;
height: 100px;
}
td.dual_size a:hover img {
width: 250px;
height: 300px;
}
It is much simpler because in this case you should not need jscripts.
thanks for the reply
but my problem is not sloved
here, when i mouse over on the image the size is not increased
this is what i used
echo '<td class="dual_size" width="15px" height="25px" id="img1" name="img1">
<a href="javscript:void(0)"><img src="' . $cimage . '"/></a></td>';
and the style sheet is
<style type="text/css">
td.dual_size a img
{
width: 170px;
height: 100px;
}
td.dual_size a:hover img
{
width: 250px;
height: 300px;
}
</style>
and i also tried like this
here the problem is, the cells in the table are not fixed at one position they are increased when i mouse over on the images
this is what i used
echo '<td border="1" width="15px" height="25px" id="img1" name="img1">
<img onmouseover="this.style.width=250;this.style.height=200"
onmouseout="this.style.width=170;this.style.height=100" width="170px" height="100px" src="' . $cimage . '"/></td>';
the main thing i need is it should Zoom In(increase) the images at the X and Y co-ordinates but the cells should not get disturbed
hope u understood my problem
waiting for the reply
[edited by: coopster at 1:17 pm (utc) on Dec. 1, 2008]
[edit reason] removed url per TOS [webmasterworld.com] [/edit]
eg:
echo '<td height="300" width="300"><table width="100%" border="0" cellpadding="0" cellspacing="0">' . "\n";
echo '<tr>' . "\n";
echo '<td class="dual_size" border="1"><a href="javscript:void(0)"><img src="' . $cimage . '" /></a></td>';
echo '</tr>' . "\n";
echo '</table></td>' . "\n";
As you see a 300x300 is set to the outside element which is enough to cover for the max width/height. Then the inner html should show as fixed because it does not overlap the width or height.
what wrong am i doing still i am facing the trouble with this
don't know why it is not increasing the image size
please help me
i tried as u said above and when i hover on the image it is not increased (Zoom In)
echo '<table border="1" align="center" width="55%" height="60%" BORDERCOLOR="#C6C6C6" >';
for($r=1;$r<=3;$r++)
{
echo '<tr>';
for($d=1;$d<=3;$d++)
{
$obj=mysql_fetch_object($result);
$imageSrc=$obj->path;
$cimage="/images/".$obj->path;
echo '<td class="dual_size" border="1"><a href="javscript:void(0)"><img src="' . $cimage . '" /></a></td>';
}
echo '</tr>';
}
echo'</table>';
and the style sheet is
<style type="text/css">
td.dual_size a img
{
width: 170px;
height: 100px;
}
td.dual_size a:hover img
{
width: 250px;
height: 300px;
}
</style>
and one thing i didn't understand what is this
<a href="javscript:void(0)"> why are u using this please tell me
You need to enclose each of the images in another element to take care of the max width/height if it is to use the zoom inline. Currently the loop that presents the images in a row uses just a <td> which means the image that zooms in, will push the adjacent images.
The <a> element is used because of the hover property. You need the hover property to perform the zoom right? The <img> element does not have a hover property.
The usual implementation for this though, is to create a popup like window instead the implementation is similar but you don't have to worry about the adjacent images because the hovered image pops up. The javascript:void(0) is like a placeholder it does nothing, you could had put a label #something and is just so the element to be html compliant.
If you want to use a css popup instead here is a sample that could help you. Create a new page test it first and finally integrate it. It does not use tables, just divs.
/* Styles */
<style type="text/css">
#zoom {
position:relative;
width:75px;
}
#zoom a.dual_class {
display:block;
width:75px;
height:75px;
}
#zoom a .zoomin {
display:block;
position:absolute;
width:0;
height:0;
}
#zoom a.dual_class:hover .zoomin {
display:block;
position:absolute;
width:300px;
height:300px;
}
</style>
/* PHP/HTML */
<?php
echo '<div id="zoom">' . "\n";
echo '<a class="dual_class" href="javscript:void(0)" title="my image"><img src="sample_image.gif" alt="No Zoom" border="0" /><img class="zoomin" src="sample_image.gif" alt="Zoom In" border="0" /></a>' . "\n";
echo '</div>' . "\n";
?>
