O.k i have edited the first 2, to edit the pics click on Picasa 3 on your desktop, find the pictures you wish to edit, click on the picture you want to edit, you are then presented with the image you have clicked on, look at the menu on the left and you can see you can add text etc, click on the "Tuning" menu above where it says "straighten" and what i do is increase the light and highlights so that the picture is more clear,also add a little shadowing as this gives the picture a sharper look, then all i do after that is click "back to library". When you have finished editing each picture, just click once on the pic you have just edited then go to file and save.
I will copy this into an email and send it to you along with the edited pics.
Here are the 2 pics i have edited for you.
oh and one last thing, if i need a loft conversion or extension, i will be contacting you.
