I am trying to export data as an image and receive the following;

Rasterize::bigraster: Not enough memory available to rasterize Notebook expression.

Here is what I have:

In[7]:= MemoryAvailable[]
Out[7]= 11704426496

In[8]:= MemoryInUse[]
Out[8]= 67415776

Not sure what is going on, but would appreciate some insight.
