I've always preferred when a site gives you a gallery of thumbnails that link to the larger image, much the way renderosity does. Sites that have slideshows or galleries of large images can really test the patience of anyone with a 56k such as myself, and I'll almost never want to go through every single image on a person's site. And make sure you know how to properly compress an image into an effecient jpg file! And last but not least, and I only say this because I don't know what your experience level is, do not upload any images that are larger than they will be on the web page, meaning that you should not use any html that will rescale your image for you rather than do it in photoshop or whatever program you might use. I've seen pages where people would take images that were like 800x600 and had them displayed at about 200x150. Some people do this for their thumbnail pages. The problem with this is the rescaled image takes just as long to load as the full size one, and images rescaled using html look god awful. If you've posted anything in renderosity galleries, however, you should already be familiar with the proper way of making thumbnails.
