I have done this. I regret that the image server is not currently on-line, but take a look at http://neosoft.com/~iai/florida/florida.htm for an example of how it would work

Yes, you are making sense. The search results should be displayed as text, preferably with a one-line title for each image. Selecting an image from this list displays an HTML catalog page with all available info about the image and a thumbnail GIF. Selecting the GIF displays a 640x480 JPEG. If you want to serve a higher-resolution image, it should be included as a separate link with appropriate warnings about file size, download time, etc.
If the search results list is too large, back up and re-do the search with more restrictions. You can also allow the user to limit the number of hits they receive.
