Apple is no longer restricting Mac OS X betas to paying developers.

Find Graphics in TextEdit .rtfd Files
Want to find the graphics in a TextEdit document in the .rtfd format? The document is actually a package - a special kind of folder that looks like a file. To see and extract just the graphics, Control-click the document and choose Show Package Contents. A new window opens showing you just the embedded images, along with a TXT.RTF file that contains the text of the file.
