Try to avoid using too many photos on a single page - if you have a large selection of photographs that you would like to use then perhaps a photo gallery is a good idea. Just chose a couple to accompany your text, you can always link to the relevant gallery section at the end of your article if people want to see more pictures.

Keep file sizes to a minimum - Resize pictures in an image editor and "save for web" before you add them to your website - do not use HTML to reduce the size of your images - using HTML to make your pictures fit may look OK but will mean that the download time of the page will be longer than it needs to be. If a page takes too long to download people will get bored very quickly and more than likely give up.

If you're sending pictures to the webmaster send them as they come off the camera rather than resizing them unless your webmaster has specified a format already - it's much easier to reduce the size of an image than it is to increase it. Also check before emailing large files - if the file sizes are too big it may be better to save them to a CD rather than sending them via email.
