When I have an page that has a lot of images, it is cumbersome to write out the jinja used to handle the images. This is a quick and dirty script to create all of the render image “tags” with the appropriate image names extracted from the images themselves. It simply dumps them to a text file where I can cut/paste to my heart’s content. An example of what it does can be seen in the header image at the top of the page.
