I'm using a marble (white/gray)background for my web page and have an image with a lot of blank space.  Is it possible to use the marble web page background as the background for the image using the transparency effect?  If so how would you do it with LView Pro?  If it can't be done any advice you can give would be great.  Thanks

Since LView supports GIF 89a, it probably fully supports GIF transparancy.  You need to load your "image with a lot of blank space".  Then, select the "blank space" color and assign it to be the transparent color for the GIF file (I'm not certain of the exact command within LView).  Save the new GIF.

Setting your transparent color should allow your background marble texture to show through.

If you need me to, I can get LView and check it out.

These instructions work for LView Pro 1B2.  There is a more recent version than this, but the process is almost the same.  The thing with LView Pro is that there isn't really a precise command that sets the transparent colour.  So, you need to follow a slightly convoluted process.

1.  On the "Retouch" menu, choose "Color Depth".  Click "Palette Image" on the top line, and choose "OK".  (Do this even if Palette Image is already selected.)
2.  On the "Options" menu, choose "Background Color".  Click the "Dropper" button.  The Background color screen will disappear, and you will be back at your image, with a cursor that looks like an eyedropper.  Click once on the image, and then draw a small box that surrounds ONLY the colour that you would like to have transparent.  It is not necessary to select every section of the colour, but the box that you draw must have inside it only the colour that is to be transparent.
3. On the "File" menu, choose "Save as".  In the bottom left pull-down, choose "GIF 89a (*.gif)".  Enter a name for your graphics file, and choose "OK".
4.  Any areas in your file that were originally in the colour that you chose in step 5 will now be transparent.  So, they will show the background colour of your web page.
