David,
this is your personal blog entry from me (David). I have resized a picture to 500 pixels wide and maintained its proportion. I paid $60 Singa dollars to learn this from a chinese computer lad in the Hunan Tecnology Mall. Check this entry over and if you have any suggestions please email and text you have done so. This will make me check the email that night. All other pictures are full size and fluked entry to site I guess.
To others, this is what you need to do, practise before leaving and do not pack your bags until the job is up to speed.
