[Resolved] Random Pic Generator with conv to thumbs

[ris]

Does anyone know where I can find a script that will choose pictures out of a directory, and then randomly dislplay them on a page but in a thumbnail size, and linkable back to the original image? I want to have some sort of "include ()" function or something inserted into my homepage, and randomly display a picture, which someone can click and see the original image. I have found a php script that will do the randomizing of the picture but being a PHP retard, I cant figure out how to make it appear in reduced size on the index.php page. Can anyone help or point me in the right direction? Thanks

I could write you a script that does just that.

Simply PayPal me $50(contact me for PayPal details) and we're golden. (KIDDING; WILL NOT ACCEPT MONEY)

Simply search for php image resize scripts, or kindly wait for someone to offer to write one up for you. I would love to do so myself, but hardly have the time 🙁

I appreciate it. I have been looking and have yet to find one. Maybe someone will have it at their fingertips. Later.

[bradgrafelman]

taps fingers You know... I'm actually not very busy at like 1AM CST... how about we get some details figured out and I try to write up somethin' for ya?

Can you give me things like...

1. All extensions to include for random image-picker. (If you want a method to exclude images from the random picker, let me know. like only include images not beginning with 'x'... "34134.jpg" will be included, but "x3413.jpg" won't be, etc.)

2. Specify 'thumbnail size'. Gimme demensions! 🙂

2a. I'll be using the GD library; you need to make sure your host supports this, AND that the image type (extension) is supported by GD.

That should just about do it... I can leave the configurable variables towards the top in a commented out section, such as the path to the directory, thumbnail size configuration, etc. etc.

If you've already found something else, or wish to continue searching elsewhere, just let me know!

I can most likely host a working example when I complete it, so you can veto/accept it, ask for changes, etc.

The script I am using accept multiple ext but we are only using jpg, which it uses also, so that part is ok. There are no specific pictures to exclude, we wil just point it to a dir and let it rip. Dimensions for the proposed thumbnail (a bit bigger) maybe like 250x 175 or something similar to that. I use abac.co as a host and im pretty sure they have the GD library..

Thank you so much for the offer. let me know if you neeed the original script or anything. although i may be going to bed here soon I could get that to you tommorow. thnkx again, c

[bradgrafelman]

Alrighty. You said the thumbnail size was to be 250x175... which of the following would you like me to incorporate into the thumbnail maker a check...

1. If the random image is less than 250x175, simply leave it alone, don't stretch it.

2. Attempt to resize the pictures proportionately as best as possible.

3. Text on either the larger/thumbnail picture, such as in the lower right corner... "Copyright 2005 <Your Name, or Your Website>".

4. Any other feature you can think of.

Guess you could just make a thumbnail out of whatever image is selected but that'll kill your server.

The best thing to do is to just make it pick an image from a folder full of thumbnails (name them the same)...something like this:

::Folders Setup::
thumbnails/
images/

::Images Setup::
thumbnails/1.jpg
images/1.jpg

Now when your randomiser selects an image it'll probably return 1.jpg from the thumbnail folder so your HTML will be:
<a href="http://www.mysite.com/script.php?image=1.jpg">
<img src="thumbnails/1.jpg"></a>

and in SCRIPT.PHP:

<?php
$image = "images/".$_GET['image']; //$_GET['image'] will equal 1.jpg
//do something with image
?>

If that makes sense then it should work.

Alternatively use the GD lib.

P.S. you aren't a PHP retard. PHP is a language for retards so your a retard in general like the rest of us.

I am thankful for the help. I will not be able to look at it and try it out until tonight after work. Later, c

<?php
header('Content-type: image/jpeg');

// --- BEGIN CONFIGURATION ---

$path = 'images/';
$width = 175;
$height = 250;

// --- END CONFIGURATION ---


$files = @glob(realpath($path) . '/{*.JPG,*.jpg,*.JPEG,*.jpeg}', GLOB_BRACE);
if($files === FALSE) die();
$filename = $files[rand(0, count($files)-1)];

list($width_orig, $height_orig) = getimagesize($filename);

if ($width && ($width_orig < $height_orig)) {
   $width = ($height / $height_orig) * $width_orig;
} else {
   $height = ($width / $width_orig) * $height_orig;
}

$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

imagejpeg($image_p, null, 100);
?>

You can thank PHP.net for most of that code.

EDIT: I assumed you'd know what to do with this code; if not, put it into a script, i.e. image.php, and point the 'path' to the correct place (you may use relative or absolute paths), then simply put <img src="image.php"> on your HTML page.

[ris]

I will try it tonight. It may take me a couple of times to tweak it etc. Once succcesful or if questions I will post either way. Thanx again for the help.

[bradgrafelman]

I will keep my subscription to this threat, then.

If you have questions that pertain to this script/thread, feel free to reply. If not, make sure you mark this thread as "RESOLVED" using the link, so that I know I can cancel my subscription.

I dont know what im doing wrong i put the code in the following linked page www.egelands.com/new.php and then I created an htm file with the reference you mentioned above at www.egelands.com/new2.htm. and I get nothing. My folder path is ce/trips/arizona. Any ideas. Thx

Change this:

if($files === FALSE) die(); 

to this:

if($files === FALSE) die('GLOB ERROR'); 

Then refresh the new.php page and tell me what it outputs (if anything).

EDIT: WAAAAAIT! 'new.php' SHOULD NOT HAVE HTML, NOR ANY OUTPUT other than the PHP code. Get rid of EVERYTHING outside of the PHP tags. This page is NOT meant to be XHTML compliant, or whatever standard you're using. THIS IS MEANT TO BE AN IMAGE; no one should ever see the source.

Make a script called phpinfo.php, make the contents this:

<?PHP
phpinfo();
?>

Gimme the url when that's done!

[bradgrafelman]

Not sure if PHP 4.3.10 includes the GD library bundle or not, but either way, your server was not compiled with the GD library.

My script relies on GD library to do the resizing. Since you do not have this, either find another server you can host this script that DOES have the GD library, or else... I don't know what to tell you 😛

Maybe try contacting the server administrator and asking him about the GD library.

Thanks for all the help. I am going to send this thread to abac.com to see if they can do something about getting GD. Thanks,
