Fix image resizing and cropping with php

t is urgent : I need to fix images cropping and resizing in php and display them in a responsive gallery Link : [login to view URL] We want to show channels images in a grid mode (responsive) with a specific image ratio : When the user upload the image, the script resize and crop it. We want to fix it to crop the maximum width or height of the image and resize it. Bid only if you can do it this is a part of the resize function : function PT_Resize_Crop_Image($max_width, $max_height, $source_file, $dst_dir, $quality = 100) { $imgsize = @getimagesize($source_file); $width = $imgsize[0]; $height = $imgsize[1]; $mime = $imgsize['mime']; switch ($mime) { case 'image/gif': $image_create = "imagecreatefromgif"; $image = "imagegif"; break; case 'image/png': $image_create = "imagecreatefrompng"; $image = "imagepng"; break; case 'image/jpeg': $image_create = "imagecreatefromjpeg"; $image = "imagejpeg"; break; default: return false; break; } $dst_img = @imagecreatetruecolor($max_width, $max_height); $src_img = $image_create($source_file); $width_new = $height * $max_width / $max_height; $height_new = ($width * $max_height / $max_width) * 1.29; if ($width_new > $width) { $h_point = (($height - $height_new) / 2); @imagecopyresampled($dst_img, $src_img, 0, 0, 0, $h_point, $max_width, $max_height, $width, $height_new); } else { $w_point = (($width - $width_new) / 2); @imagecopyresampled($dst_img, $src_img, 0, 0, $w_point, 0, $max_width, $max_height, $width_new, $height); } @imagejpeg($dst_img, $dst_dir, $quality); if ($dst_img) @imagedestroy($dst_img); if ($src_img) @imagedestroy($src_img); } Thank you !
