title: How to make image loading from Mysql faster?
body: <p>recently i have tried to store images in Mysql database (use BLOB data type), using php and web to upload and store it. It works fine, except when loading large enough image , it is going to load very slowly. Is there any way to load this image faster ? </p>
  
  <p>note : my friend suggests me to use force caching to this image ( he says something about change the content-header of image ), but i don't know how to do it. and i doubt it will bring significantly better performance. </p>
  
  <p>Thanks in advance </p>
