title: php upload image, rename, thumbnail, and save both
body: <p>Ive been looking at the move_upload_files function, but i dont think thats what i need.</p>
  
  <p>I need to upload a picture (max size 2mb png, jpg, gif only) then rename it, then create a thumbnail of it, and save both to the same directory. I figure ill upload/rename the main file first, then take that and create the thumbnail. But what functions should i be looking at to do this?</p>
