Yes, Jessops will print them for you but why not print them yourself. Get some Instant Dry Glossy Photo paper from click here and experiment. If you don't have a programme that will print images like MS Publisher, Paint Shop Pro or Photoshop download the free Irfanview from click here and try that. Once you get in to it you will find it is addictive.
I did a bit of research earlier in the year and Bonus Print came out cheapest. I've also used them and the photos were great (very prompt too). Which? didn't rate them very highly in their survey but I say the proof is in the pudding, so it's Bonus Print for me.
