Image Dimension Restriction

Not an exact solution to your issue but you can restrict users to uploading minimum file size by adding this code to your functions.php


add_filter('wp_handle_upload_prefilter','tc_handle_upload_prefilter');
function tc_handle_upload_prefilter($file)
{

    $img=getimagesize($file['tmp_name']);
    $minimum = array('width' => '400', 'height' => '400');
    $width= $img[0];
    $height =$img[1];

    if ($width < $minimum['width'] )
        return array("error"=>"Image dimensions are too small. Minimum width is {$minimum['width']}px. Uploaded image width is $width px");

    elseif ($height <  $minimum['height'])
        return array("error"=>"Image dimensions are too small. Minimum height is {$minimum['height']}px. Uploaded image height is $height px");
    else
        return $file; 
}

This example has the minimum set to 400 by 400 but you can change it to whatever you want. :slight_smile:
