title: What image format can c# load fastest?
body: <p>this may seem like an odd question, and I don't know the formats of images so I'll just go ahead and ask...</p>
  
  <p>I'm making a minesweeper game (relevant to different things too) which utilizes a grid of buttons, then I'm adding a sprite to the buttons using <code>backgroundImage</code>. If the grid is 9x9 it's fine. 15x15 it slows down and 30x30 you can visibly see each button being loaded. </p>
  
  <p>That raises me to my question: Which image format would load fastest? Obviously, file size takes a part in the loading speed, however, I am enquiring as to if, say, a jpeg - with the same filesize as a gif - will load faster. or a bmp, png, etc.</p>
  
  <p>I'm asking this as to see if I can get my grid to load faster using a different format.</p>
  
  <p>Thanks!</p>
