[Plugin: NextGEN Gallery] Solution of memory limit

I have a solution of error in memory limit t use gd in large images:

admin/functions.php
replace:

// save temp file to gallery
						if ( !@move_uploaded_file($temp_file, $dest_file) ){
							nggGallery::show_error(__('Error, the file could not be moved to : ','nggallery') . $dest_file);
							nggAdmin::check_safemode( $gallery->abspath );
							continue;
						}

to:

// fix error memory with big images
					if($imagick_t = new Imagick($temp_file)){
						$imagick_t->thumbnailImage(900, 900, true); /* Resize to 900x900 */
						$imagick_t->writeImages($dest_file, false); /* rewrite */
						$imagick_t->clear();
						$imagick_t->destroy();
					}else{

						// save temp file to gallery
						if ( !@move_uploaded_file($temp_file, $dest_file) ){
							nggGallery::show_error(__('Error, the file could not be moved to : ','nggallery') . $dest_file);
							nggAdmin::check_safemode( $gallery->abspath );
							continue;
						}
					}

Replace:

// save temp file to gallery
			if ( !@move_uploaded_file($_FILES["Filedata"]['tmp_name'], $dest_file) ){
				nggAdmin::check_safemode(WINABSPATH.$gallerypath);
				return __('Error, the file could not be moved to : ','nggallery').$dest_file;
			}

to:

// fix error memory with big images
		if($imagick_t = new Imagick($_FILES["Filedata"]['tmp_name'])){
			$imagick_t->thumbnailImage(900, 900, true); /* Resize to 900x900 */
			$imagick_t->writeImages($dest_file, false); /* rewrite */
			$imagick_t->clear();
			$imagick_t->destroy();
		}else{
			// save temp file to gallery
			if ( !@move_uploaded_file($_FILES["Filedata"]['tmp_name'], $dest_file) ){
				nggAdmin::check_safemode(WINABSPATH.$gallerypath);
				return __('Error, the file could not be moved to : ','nggallery').$dest_file;
			}
		}
