good day to everyone.
ive been having some troubles with the code a certain gentleman has posted about image gallery. here was the code he posted:
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.
