Common scenario when rendering is to have some materials use custom image files. I have included the 3 most common areas to check should you receive the “The following render appearance images are missing:” warning when rendering below:
1. As a best practice try to store all custom image files in one location. Wherever these image files are located, ensure that the path is specified under Options > Rendering > Additional Render Appearance Paths.
Add the path[s] where the images are stored here, and then re-render the scene to see if the warning persists.
2. If the materials are stored on a network location, verify the location appears in the list above as an additional render appearance path. Also make sure all users have access to this folder.
3. Depending on the application which created or saved the image file the material uses, Revit may not be able to load the image file for rendering. In most cases this may occur with certain JPEG compression modes and will generate the same warning message at render.
One easy test is to open the image file and save it as .PNG format instead. Edit the Revit material to point to the .PNG format image to see if this eliminates the warning when rendering.

A great post! I didn't know about the image compression. Could you perhaps write some tips on creating custom images? I'm working on a model with some custom marble. We have a 1'x1' sample from the stone yard. I know to create a custom rendering material by scanning the sample. The challenge is that in a large marble application such as custom stone faced desk, this 1x1 image will show the pattern repeat. What is an approach to making the pattern repeat less obvious?

This is very helpful, if the image is something you have created and know where it is.
However, what about the case where you have an image you can't to locate? Is there a way to backtrack this a bit and determine what material in Revit is calling the offending image? Some sort of material export utility or something? It would be nice if they could provide a "More Info" option in the dialog which would provide this sort of info.

Yes you can, I’ll be publishing a blog post on this one tomorrow morning. The latest Revit journal file will list the full image path, for each image which cannot be located. Search the journal file for the image name, located [for Revit Architecture] at : “C:\Program Files\Autodesk Revit Architecture 2010\Journals”. Check back tomorrow for the full post!
