Random photo

[tommykjensen]

Does anybody have a little script that can choose a random thumbnail and copy it to a specific location?

Please wait couple of hours.

Place the files on your gallery root. Text document and demo file explains usage and parameters.

It's now 3 am here, so I'll comment comments and questions tomorrow morning. This is just a small extra. I'll post a bug fix pack tomorrow, it has duplicate photo removal from combined exhibitions and important bug fix for internal ftp etc.

Thank you very much Pekka,

Another great feature.

Thanks for the work you put into it, I know this will be usefull for my site.

Thank You very much this is usefull however it was not what I was looking for - but thats my fault I didn't explain it well enough what I wanted to use it for.


What I would like is the ability to put an url such as www.domainname.com/gallery/random.jpg in signatures on a forum like this.

In the background on my server I would run the script once an hour or so in order to change the thumbnail in random.jpg. This way my signature (or avatar) would change fom time to time.

great, pekka!
this could be a solution for my problem (latest three photos and random photos on the main page of the gallery).

it works well with an external index.php file as starting page for my site.
but what, if i want to include these snippets into EE's own index-file (indexstyles/1.php for example)?
this obviously does not work.

how could this be done?

Or how about a dynamic signature such as this one

just with 3-5 microthumbs instead of statistics?

[tommykjensen]

Here is a simple random photo script. Schedule it to run at the interval of Your choice.


<?php
srand ((double) microtime() * 1000000);

$path = "ee/photos/thumb";

$handle=opendir($path);
while ($file = readdir($handle)) {
if ($file != "." && $file != "..") {
if (strpos(strtoupper($file), ".JPG") > 0) {
$jpgfiles [] = $file;
}
}
}

$randnum = rand(0,count($jpgfiles));

$image = $path . "/" . $jpgfiles[$randnum];

$im = imagecreatefromjpeg($image);
Imagejpeg($im,'random.jpg',100);
ImageDestroy ($im);

?>

EDIT: Slightly improved code.

Once again I have improved the code. It is highly likely that someone better than me can optimize the code.


<?php

$path = "ee/photos/microthumb";

$handle=opendir($path);
while ($file = readdir($handle)) {
if ($file != "." && $file != "..") {
if (strpos(strtoupper($file), ".JPG") > 0) {
$jpgfiles [] = $file;
}
}
}

$image1 = $path . "/" . $jpgfiles[array_rand($jpgfiles)];
$im1 = imagecreatefromjpeg($image1);
$ix1 = imagesx($im1);
$iy1 = imagesy($im1);

$image2 = $path . "/" . $jpgfiles[array_rand($jpgfiles)];
$im2 = imagecreatefromjpeg($image2);
$ix2 = imagesx($im2);
$iy2 = imagesy($im2);

$image3 = $path . "/" . $jpgfiles[array_rand($jpgfiles)];
$im3 = imagecreatefromjpeg($image3);
$ix3 = imagesx($im3);
$iy3 = imagesy($im3);

$image4 = $path . "/" . $jpgfiles[array_rand($jpgfiles)];
$im4 = imagecreatefromjpeg($image4);
$ix4 = imagesx($im4);
$iy4 = imagesy($im4);

$height = $iy1 + $iy3 + 3;
if ( $iy2 + $iy4 > $height ) {
$height = $iy2 + $iy4 + 3;
}
$heightl1 = $iy1;
if ( $iy2 > $iy1 ) {
$heightl1 = $iy2;
}
$heightl2 = $iy3;
if ( $iy4 > $iy3 ) {
$heightl2 = $iy4;
}

$length = $ix1 + $ix2 + 3;
if ( $ix3 + $ix4 > $length ) {
$length = $ix3 + $ix4 + 3;
}

$offsety1 = 0;
$offsety2 = 0;
$offsety3 = 0;
$offsety4 = 0;

if ( $iy1 < $iy2 ) {
$offsety1 = ($iy2 - $iy1 ) / 2;
}
if ( $iy2 < $iy1 ) {
$offsety2 = ($iy1 - $iy2 ) / 2;
}
if ( $iy3 < $iy4 ) {
$offsety3 = ($iy4 - $iy3 ) / 2;
}
if ( $iy4 < $iy3 ) {
$offsety4 = ($iy3 - $iy4 ) / 2;
}

$offsetx1 = 0;
$offsetx2 = 0;
$offsetx3 = 0;
$offsetx4 = 0;

if ( $ix1 < $ix3 ) {
$offsetx1 = ($ix3 - $ix1 ) / 2;
}
if ( $ix2 < $ix4 ) {
$offsetx2 = ($ix4 - $ix2 ) / 2;
}
if ( $ix3 < $ix1 ) {
$offsetx3 = ($ix1 - $ix3 ) / 2;
}
if ( $ix4 < $ix2 ) {
$offsetx4 = ($ix2 - $ix4 ) / 2;
}


$im = imagecreatetruecolor($length,$height);

imagecopy($im, $im1, 1 + $offsetx1,1 + $offsety1,0,0,$ix1, $iy1);
imagecopy($im, $im2, 1 + $offsetx1*2 + $ix1,1 + $offsety2,0,0,$ix2, $iy2);

imagecopy($im, $im3, 1 + $offsetx3,2 + $heightl1 + $offsety3,0,0,$ix3, $iy3);
imagecopy($im, $im4, 1 + $offsetx3*2 + $ix3 + $offsetx4,2 + $heightl1 + $offsety4,0,0,$ix4, $iy4);

Imagejpeg($im,'random4thumbs.jpg',100);
Imagejpeg($im,'',100);
ImageDestroy ($im);
ImageDestroy ($im1);
ImageDestroy ($im2);
ImageDestroy ($im3);
ImageDestroy ($im4);
?>
