Creating a web page of your collection is very easy.

Nearly all internet service packages include some web space. Uploading your collection to the web will provide a service to the community in addition to providing a backup of your information. Documenting your valuables is important for insurance purposes. If your house burned down, and took all your coins AND your computer with it, you could still have those images you'd uploaded to the web.

If you're using other folks' images, be sure to get permission beforehand. I've found they are nearly always happy to let you do this; it is a compliment to their photographic skills, and it can provide them some very valuable publicity.

Copy image, paste it into a document, add your text, then save-as->html

Uploading to the web will depend on your Internet Service Provider, so you will have to consult them for details, but I promise it will be a painless process.
