PHP Slide Show Bug

[kbphoto]

Greetings

I have a slide show on our website that was built by a friend who hit a stumbling block on this bug. I was hoping someone may recognize the issue.

The website is http://www.KarenImages.com. Each page has a slide show. When a page is open and running in a browser and you open a new tab and browse that tab & then come back a minute or so later the slide show quickly does a catch up pattern rapidly playing all the images missed while on the other tab in order to catch up to where it is supposed to be. Codepen did not have a php option so I did not create one for this (newbie). The code for the home page slide show is pasted her – each page has a unique image directory and php file that is behaving the same way. this php code is from the file “home-fading.php”

Second issue is the slide show is warping the images slightly in the horizontal dimension…I am thinking this is an image size issue???

Any ideas greatly appreciated!

============================================================

$folder = opendir(“../ss_home_images/”); // Use ‘opendir(“.”)’ if the PHP file is in the same folder as your images. Or set a relative path ‘opendir(“../path/to/folder”)’.

$pic_types = array(“jpg”, “jpeg”, “gif”, “png”);

$index = array();

while ($file = readdir ($folder)) {
if(in_array(substr(strtolower($file), strrpos($file,”.”) + 1),$pic_types))
{
array_push($index,$file);
}
}

closedir($folder);
//print_r($index);
$active=’class=”active”‘;

shuffle($index);
foreach($index as $img)
{
if($active!=””)
{
?>

First issue is a JavaScript issue. I think the `setInterval()` function calls build up when tabbed. You can try changing:

$(function() {
setInterval( “slideSwitch()”, 5000 );
});

into

$(function() {
var id = setInterval(slideSwitch, 5000);
$(window).blur(function(){
clearInterval(id);
});
$(window).focus(function(){
id = setInterval(slideSwitch, 5000);
});
});

to cancel the interval when the window loses focus and resume when it gains focus. (I haven’t tested this but it could work)
