I'm guessing that most people who read TIFF, JPEG, and GIF images from
disk actually want to *display* the images in IDL. Hence, I wrote a
procedure which makes it rather easy.

SHOWIMAGE displays images in GIF, BMP, PICT, TIFF, or JPEG format (the
format is detected automatically), e.g.

IDL> file = filepath('rose.jpg', subdir='examples/data')
IDL> showimage, file

Check it out at:

Note that IDL 5.2 is required, to allow automatic detection of image
format (i.e. the query_gif, query_bmp etc. functions in IDL 5.2 are
used).

Cheers,
Liam.
