This simple-to-use graphics editing software is included as part of the OpenOffice Suite.
Introducing Draw
While other office suites may leave graphics editing programs out of their complete suite, OpenOffice includes Draw. Draw is a simple-to-use photo and graphics editor. Think of Draw as a souped-up version of MS Paint where you can create and edit professional-level images quickly and easily.
The best part is that, as part of the Open Office Suite, Draw is completely free to download and use.
