+# PHP - smart&easy image resize function
+
+* resizing an image with 1 simple function.
+* more stuff - visit my blog : www.nimrodstech.com
+
+## How to use : (code snippet)
+
+```php
+      //indicate which file to resize (can be any type jpg/png/gif/etc...)
+      $file = 'your_path_to_file/file.png';
+
+      //indicate the path and name for the new resized file
+      $resizedFile = 'your_path_to_file/resizedFile.png';
+
+      //call the function (when passing path to pic)
+      smart_resize_image($file , null, SET_YOUR_WIDTH , SET_YOUR_HEIGHT , false , $resizedFile , false , false ,100 );
+      //call the function (when passing pic as string)
+      smart_resize_image(null , file_get_contents($file), SET_YOUR_WIDTH , SET_YOUR_HEIGHT , false , $resizedFile , false , false ,100 );
+
+      //done!
+```
+
+## Funcion call (with doc)
+
+```php
+   /**
+   * easy image resize function
+   * @param $file - file name to resize
+   * @param $string - The image data as a string, default is null
+   * @param $width - new image width
+   * @param $height - new image height
+   * @param $proportional - keep image proportional, default is no
+   * @param $output - name of the new file (include path if needed)
+   * @param $delete_original - if true the original image will be deleted
+   * @param $use_linux_commands - if set to true will use "rm" to delete the image, if false will use PHP unlink
+   * @param $quality - enter 1-100 (100 is best quality) default is 100
+   * @return boolean|resource
+   */
+  function smart_resize_image($file,
+                              $string = null,
+                              $width = 0,

+
+### Thanks for all the people adding more functions! keep it going
+
