Turning off and on images in figures 2

Question

I am having troubles with the draft command in the graphic package.

\usepackage[draft]{graphicx}

My document is large so I don't want just the images to load, but want to keep the rest of the text formatting I have setup through the href package. I found this document, but when I try I get an error code.

Thanks for looking!

Answer 1

While some of the suggestions provide ways to avoid placing the actual image into the document, a number of them still require the image to be read from the disk or some such overhead. Since the desire was to avoid accessing the disk for each image, I instead propose redefining \includegraphicsas follows:

\renewcommand\includegraphics[2][]{\fbox{Image}} 

In this way, a placeholder is placed in the document, but the overhead of searching the disk for the image or its directory entry is wholly avoided.

As we see from the result below, instead of the image, a small \fbox is inserted.
