Нашёл на просторах интернета замечательный класс для работы с изображениями - SimpleImage, и адаптировал его к Eleanor CMS. Поскольку встроенные средства для этого у RC5 мягко говоря слабенькие.

The first example below will load a file named picture.jpg resize it to 250 pixels wide and 400 pixels high and resave it as picture2.jpg
<?php
include $Mainclass->root_path.'classes/others/class_simpleimage.php';
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resize(250,400);
$image->save('picture2.jpg');
?>

If you want to resize to a specifed width but keep the dimensions ratio the same then the script can work out the required height for you, just use the resizeToWidth function.
<?php
include $Mainclass->root_path.'classes/others/class_simpleimage.php';
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToWidth(250);
$image->save('picture2.jpg');
?>

You may wish to scale an image to a specified percentage like the following which will resize the image to 50% of its original width and height
<?php
include $Mainclass->root_path.'classes/others/class_simpleimage.php';
$image = new SimpleImage();
$image->load('picture.jpg');
$image->scale(50);
$image->save('picture2.jpg');
?>

You can of course do more than one thing at once. The following example will create two new images with heights of 200 pixels and 500 pixels
<?php
include $Mainclass->root_path.'classes/others/class_simpleimage.php';
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToHeight(500);
$image->save('picture2.jpg');
$image->resizeToHeight(200);
$image->save('picture3.jpg');
?>

The output function lets you output the image straight to the browser without having to save the file. Its useful for on the fly thumbnail generation
<?php
header('Content-Type: image/jpeg');
include $Mainclass->root_path.'classes/others/class_simpleimage.php';
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resizeToWidth(150);
$image->output();
?>

The following example will resize and save an image which has been uploaded via a form
<?php
if( isset($_POST['submit']) ) {
include $Mainclass->root_path.'classes/others/class_simpleimage.php';
$image = new SimpleImage();
$image->load($_FILES['uploaded_image']['tmp_name']);
$image->resizeToWidth(150);
$image->output();
} else {
?>
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="uploaded_image" />
<input type="submit" name="submit" value="Upload" />
</form>
<?php
}
?>
