I have Adobe Photoshop 7.0.  I have several images that are all on a
white background and I need the background to be transparent.  Each
image is either black or blue solid line drawrings so these aren't
complex images, mostly spirals and loops and all have a solid white
background.  Is there a way to make the white background be replaced
by a transparent background for the entire area?  Some of the designs
are loopy so that the white on the inside of the design will also need
to be replaced so I'm trying to avoid having to do each one manually
as the shapes and loops are all different dimensions.  I'm familiar
with using the BATCH system of Adobe but again, these aren't all in
the same spots and of the same shapes so I'd need to be able to remove
ALL of the white background and replace it with tranparency.

Easily done.  First, convert the background layer to a regular layer
with "Layer/New layer/From background".  Now select the "Magic Wand"
tool and make sure "contiguous" is UNchecked in the toolbar.  Click on
a piece of the white background -- now all the white areas of the
image are selected.  Switch to the "Eraser" and scribble all over the
image.  Voila!  One transparent background...

1. Layer>Duplicate Layer (you will get a layer named "Background
copy")
2. Turn of the display of the "Background" layer (click on the eye
left to the layer in the Layers palette
3. Make sure "Background copy" layer is selected in the Layers
palette... Select>Color Range>Use the picker to select the background
color and experiment with Fuzziness settings to get the optimal
results.
4. Press delete key.

You're done.

Bad news is that you'll have to edit each bitmap individually.
