I have great problems with my logo. I create one at 460 pixels width by 60 pixels height and set the Picture Properties to be width=100%, height=60 pixels. But I find that when the browser resizes the image, the image looks unprofessional because you can see the pixels and the image is not as clear as when in Photoshop 6.0. What size should the Logo be ideally? Also, a very unusual event happens when I first access my site and the Logo is twice as wide as it should be, BUT when I right click the logo and click on Properties, the logo magically reverts back to its intended size!!!! Is this a bug in Outlook or Photoshop?? My url www.spanishcosyhomes.com Thanks, Paul
