Where should I upload my image assets or files?

The best place to upload files to Basecamp is within the Docs & Files section that you can see within the project.

Here you can upload files such as images, videos and ad copy. You also have the ability to link to files contained on cloud storage sites such as Box, Dropbox, Google Drive & OneDrive.

For data lists, we'd recommend password protecting these files and sending the passwords via a separate channel such as email.
