</body>
</html>
ive been trying to study the code yet still no luck.
my goal is:
1. go get the images loaded in their original size -(some of my images have small texts that people cant read em.)
2. get the images sorted by number -(the script displays the images in random order -_-)
anyhelp would be greatly appreciated. oh and im still a newbie in php. so please do give me a good and simple one. Thanks and good day.
Re: [PHP] image gallery problems
well every part of the code got it own comment so which part of it you dont get it ?
Re: [PHP] image gallery problems
I think this line is addressing issue 2 if I understand you correctly
$image = '<img id="view" src="' . $images[$image_view - 1]['name'] . '" width="512px">';
or possibly this one
echo '<table id="images" width="500px" border="0" cellpadding="2px">';
Just try and remove or increase any width.
and as for issue 1 you need to sort the $images array
