I have created a new plugin that automatically creates links to a image so you can paste them into forum posts, other websites, etc.
The format of the links is based on templates and can use a number of merge fields (image name, date, title, description, album, etc) can can use HTML, BBCode, or any other kind of markup. The generated code appears in a textbox anywhere on an image page. When you click on the text inside the box, it will automatically be highlighted.
