  Tip: Optimise images

  We estimate potential to save at least 225kB* by optimising images:

  1. Hero%20fleet%20v2.jpg is 282kB and could be 22kB smaller
  2. Hero%20hartlepool%20... is 261kB and could be 33kB smaller
  3. Hero%20Caroline%20v3... is 260kB and could be 20kB smaller
  4. hero%20portsmouth%20... is 244kB and could be 19kB smaller
  5. Hero%20alliance.jpg is 202kB
  6. Hero%20explosion%20v... is 184kB and could be 21kB smaller
  7. Gift%20shops.jpg is 179kB and could be 44kB smaller
  8. Hero%20Silent.jpg is 168kB
  9. Hero%20x24.jpg is 165kB
  10. Hero%20Sciencev2.jpg is 164kB
  11. Schools.jpg is 75kB and could be 47kB smaller
  12. Support%20Us%20cropp... is 59kB and could be 20kB smaller

  First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

  Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.
