Space on your web host's server is limited and expensive. Uploading pictures to your website takes up a lot of space. For this reason, it sometimes makes more sense to host your pictures somewhere else. I have found that the most cost-effective service is flickr. With a flickr PRO account ($24.95 for a year) you get a 2GB monthly upload limit, unlimited storage and bandwidth and permanent archiving. What's even better is that you can link to pictures on your flickr account from your blog and not use up any storage or bandwidth space on your server.

To link to a flickr image:

1. Login to your flickr account.
2. Go to the page of the picture you want to link to.
3. On the picture page, under "Available Sizes" choose the size picture that you want to post on your site,
4. Scroll down to "To link to this photo on other websites you can either:"
5. Copy the code in box #2 and paste this HTML into your webpage.
