Large and high quality images generally take time to load. Research shows that an Internet users spend on average 3 seconds on a new page - if your site is cluttered with images he might be long gone before they even get loaded. Not using images at all would not be recommended in the Tourism industry though as the tourists travel to experience and see new places! The key with image optimisation is to get the right balance between loading time and image quality.
Online imagery use the RGB colour mode. This is different from print imagery and photography which use the CMYK colour mode. Keep it in mind when you are thinking about printing your logo designed for the web or thinking about putting your brochures online!
