Look is used mainly for displaying molecular structures and predicting protein structure. It is especially good at multiple sequence alignment and showing the relationship between sequence and structure.
Look also has a hypertext electronic lab notebook built in so you can easily make notes of the work you do, and easily refer back to each structure
If you need to do this, try a program like Insight, Sybyl, Dock, or Autodock.
Image Output Format
Look can write output files in GIF, PostScript, PICT formats. The resolution is not as good as with other programs like Sybyl, Insight, VMD, Raster3D.
