What am I doing wrong? (Clikpic users please)

[SJKPhotography]

To all,

I'm currently having an issue with my Clikpic account. After resizing for my site and then uploading, my images are becoming very heavily pixelated and reduced in quality. Has anyone else had this? Am I using the wrong file type maybe? A setting in Clikpic that I have missed?

Below is an example, look around the 'Aon' logo on the side of the car and the sponsor logo above the rear wheel.

Thanks for your time.

Exactly the same image on Photobucket...

looks like the image has been compressed by clickpic maybe?

That's what I'm thinking Neil.

I've been in touch with their support to see if they can tell me why.
