If you want to upload a lot of documents to Google Docs, it's difficult to upload them one by one. You can send the documents by email, but this option is not very reliable and not all the formats are supported.

Phatch (works on Windows, Linux and Mac OSX) is a simple to use GUI Photo Batch Processor which handles all popular image formats. Phatch can batch resize, rotate, apply perspective, shadows, rounded corners, and more. Also, it allows you to use EXIF and IPTC tags for renaming and data stamping.
