Perhaps it's related to permissions on the folder?

Can you post a link so that we can see the problem?

Check the permissions on your files folder, it probably got set to read only. Change that and you should be good to go.

My image gallery was set up per O'Reilly's "Using Drupal" book.

Directory Permissions are 755.
File Permissions are 664.

The same as on the previous server.

The file system has been configured in drupal. The content type field path has been set in drupal.

I can confirm that new imagecache presets are created in /files/imagecache.

I can create new content and see the image while in the gallery or editing the node but can do neither for previously created nodes.

During the course of this migration I went from a single code base/site to a single code base/multi-site. So what used to be sites/all/files is now sites/example.com/files

Personally, I always put the "files" directory in the root directory for the site and usually incorporate some form of the individual site name in the directory name. E.g., if the site was MySite.com the files directory would be in the root directory and named something like "files-ms." This configuration breaks the tie between the actual site name and the file location.

I suspect that your file references are to their old location in /sites/all/files. You might be able to create a symlink for /sites/all/files and have it point to their new location. The other alternative is to manually update the references.

Hope this helps, good luck,

I had to execute the following sql statement in phpmyadmin

update files set filepath = replace (filepath, "old path", "new path");
