I'm using Ubuntu Linux, apache 2.2, php 5.2.6
I want to make a auto gallery. You put files in one directory, php script looks in that directory and makes a simple gallery.
I want it to be done without writing to hard drive. I have found a script that creates thumbnails and writes them to some other directory. I modified the script so instead writing on disk it returns array of pictures.
<?php function createThumbs($pathToImages, $thumbWidth) { // open the directory $dir=opendir($pathToImages); $i=0; // loop through it, looking for any/all JPG files: while(false!==($fname=readdir($dir))) { // parse path for the extension (jpg) $info=pathinfo($pathToImages.$fname); // continue only if this is a JPEG image if (strtolower($info['extension'])=='jpg') { // load image and get image size $img=imagecreatefromjpeg("{$pathToImages}{$fname}"); $width=imagesx($img); $height=imagesy($img); // calculate thumbnail size $new_width=$thumbWidth; $new_height=floor($height*($thumbWidth/$width)); // create a new temporary image $tmp_img[$i]=imagecreatetruecolor($new_width, $new_height); // copy and resize old image into new image imagecopyresized($tmp_img[$i], $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height); $i++; } } // close the directory closedir($dir); return $tmp_img; } ?>The problem is that I don't know how to put these pictures in html. For example if I try directly, let's say for first two pictures in array:
<html> <body> <?php $picture=createThumbs("pictures/", 140); imagejpeg($picture[0]); imagejpeg($picture[1]); ?> </body> </html>The output I get is raw, just a bunch symbols for each picture.
I have read that people used the Header("Content-type: image/jpeg") function, but I'm not sure that I understand how it works. Nevertheless, I tried it, I put it on the beginning of php script. Now the output gives the first picture, but not the second picture, so I don't know how should I get the rest.
Ideally I would like to have an option to put it in html like <img src=from_array> but I don't know how to do that.

How would I implement latex on my site (much simpler than BB)?
And once implemented how would I use it?
