title: What is the complete list of valid file extensions for images?
body: <p>And the images I'm referring to are the ones that can be embeddable in a web browser not .tif, .psd, etc.</p>
  
  <p>So the only ones I'm aware of are .png / .jpg / .jpeg / .gif / .bmp</p>
  
  <p>are there any more?</p>
  
  <p>Reason why I need this info is to only allow valid images to be uploaded in my php file upload script.</p>
