Set up initial gimp (2.6) drawing
 
I have an image gif for a base layer, which I am able to create. Now I want to create a 2nd layer which will allow me to see the base layer and allows me to also draw lines/circles on second layer. I need to see the base layer below to reference the begin/end of lines. I have done enough reading I should not be confused but am. Can someone help here? When I try to get a transparent layer created as 2nd, I get the checker board or I get the layers swapped. U C I am confused!

Umm, hi,

It surprises me that you did ave quite some views, but no reply yet...
This thing is easy:

- open Gimp
- open your image
- make a new image (File/New) - the new image should inherit the sizes of your last (open) image
- focus (click on the titlebar) on the loaded image
- choose Select-All
- choose Edit-Copy
- Focus on the new (empty) image
- select Edit-paste As...-new layer
- make a new layer (in the layers view right-click and select "new')
- pull the opacity slider all the way back until your new layer is "invisible"
- draw!!!
If you dont see the Layers toolbox, select Window/Toolboxes-Layers or hit Ctrl-L

Hppy Gimpin'!!!

My apologies I neglected to mention I need to save the original image without any changes and to save the layer with lines and circles as just lines/circles and some reference marks for the corners, I guess, So I can have an overlay reference made.
I hope that doesn't change the sequence list Thor made to much.

No it does'nt, it thus add to the sequence, what I suggest is to save the drawing as Gimp image, then either make the guide layer (the picture) invisible (poke the eye out next to the layer, or select and delete the layer (radical but possible) or (even better) create yet an other image (same dimensions should be applied right away) and select transparency in the advanced options, then select the required layer-select all-edit & copy- go to the transparent image and apsete as layer...

You should be able to save this as GIF or (even better) PNG who support transparency...

Let me know if that's not quite what you're looking for :)

Thanks Thor, last night I found a couple of sites and with what you provided I came up with a REAL DUMMIES guide for myself. I tried to verify everything but may have introduced errors when writing. If anyone finds an error or something is unclear, please let me know.
Code:

SET UP
------
1) Open GIMP.
  If there is an image file to use as a template for drawing:
        SELECT "Open" from the "File" menu.
        LOCATE that image file.
        SELECT "Open" from the "Open Image" dialog.
  If drawing without an image:
        SELECT "New" from the "File" menu to create a new image.

2) If there is a image file:
        PRESS CTRL-L, brings up the Layers panel.
        CLICK "Background" layer the Layers panel.
  To make the base image semi-transparent and allow the bottom
    layer to be seen when drawing on above layer(s):
        Enter "50" in the "Opacity" text field
        CLICK on the "Lock" check box to prevent accidentally
          drawing on this layer.

3) To open the New Layer dialog box:
        PRESS "Shift-Ctrl-N" on the keyboard
          (alternatively CLICK Layer > New Layer in the GIMP dialog).
        Type "Draw-1" in the "Layer Name" field.
        SELECT "Transparency"
        CLICK "OK."

4) To zoom into the image as needed:
        CLICK the "Zoom" menu at the bottom of the image window.

USING PAINTBRUSH
----------------
1) From the Toolbox:
        SELECT the "Paintbrush Tool"
  To create a thin line:
        ENTER "3" next to "Circle" by "Brush" in Paintbrush panel
        The number indicates the diameter in pixels (3 here).

2) Test brush width by dragging a short stroke  across the canvas.
  Compare its width to the background image features.
        SELECT a larger/smaller brush width as needed.

3) Draw the lines of artwork using the mouse.
  Need not trace the original artwork, but use the background image
    as a guide for a new drawing.

4) To draw straight lines:
        CLICK the left mouse button at the start of a line.
        PRESS & HOLD SHIFT key while moving the mouse to end point.
          (a dashed line will appear between the start point and each
          new mouse position)
        RELEASE SHIFT key and the line will be drawn.
  or
        CLICK left mouse button at the start of a line.
        MOVE mouse to next point.
        PRESS SHIFT KEY  (dashed line appears)
        CLICK left mouse button to create the line.

5) To undo a brush stroke as needed.
        PRESS "Ctrl-Z" once for each older stroke

USING PATHS TOOL
----------------
1) From the Toolbox:
        SELECT the "Paths Tool"
  To create a starting anchor point:
        CLICK the mouse at the start point for a new line.
  To create successive anchor points:
        CLICK again at points along the line and successive anchor
          point appear, with a line connecting successive points.

2) To move anchor locations:
        CLICK & DRAG an anchor point.
        The connecting lines will adjust themselves accordingly.
  To bend the line:
        CLICK & DRAG the line between anchor points to bend the line.

3) To close the path:
        PRESS "Enter"  (Don't press "Enter" until completing path)
        The successive points between the first and last points will
          be connected by a dashed line.

4) To create the final line:
        CLICK the "Edit" menu
        SELECT "Stroke Path"  (line will be created over path drawn.)
5) To open "Choose Stroke Style":
      SELECT "Stroke Selection" from the Edit Menu
      TYPE  line width in the text field.
      CLICK the "Stroke" button and the stroke will be applied to
        the line on the path.

6) To draw on another layer:
      CLICK "New Layer" in the "Layer" menu.
      Begin drawing another path.

  NOTE: applying a stroke to the path on any layer, all paths on
        that layer will be transformed to the new stroke.

DRAWING SHAPES
--------------
1) Add a new layer to the drawing from the "Layer" menu.
        CLICK the "Rectangle Select Tool" for rectangular or
              the "Ellipse Select Tool" for circular shapes.
        Drag the tool over the canvas to create the shape.

2) To draw strokes:
        CLICK the "Edit" menu, and then "Stroke Selection."
        ENTER value in the "Stroke Line" field.
        This value is in pixels, use a value similar to what was
          used for brush tool i.e. 3 pixels.
        CLICK "Stroke."

3) To create a copy of a shape on a layer:
        SELECT a "SELECT" tool from Toolbox Menu
        ENCOMPASS the object to be copied
        SELECT "COPY" from "EDIT" menu
        CLICK & DRAG the copy area to a new location
        SELECT "PASTE" from "EDIT" menu

4) To translate or transform an image
        SELECT a "SELECT" tool from Toolbox Menu
        SELECT image to change shape (encompass it with select tool)
        SELECT IMAGE > TRANSFORM from GIMP Dialog
        SELECT one of the Rotation options
  Rotate panel opens:
        ENTER "Angle" (if arbitrary angle selected)
        ENTER (optional) X,Y position
        CLICK "Rotate"

5) To get rid of dashed lines surrounding selected images:
        CLICK in unbounded area of layer until last boundary removed

SAVE OR REMOVE LAYER
--------------------
1) To remove any Layer:
        CLICK the Layer in the "Layers" Panel (CTRL-L).
        CLICK "Delete Layer" in the "Layers" Panel.

2) To save any Layer:
        CLICK the Layer in the "Layers" Panel (CTRL-L).
        CLICK on one of the 4 "SAVE" options in the "EDIT" Menu.

Glad to read you've found a way out of the maze, by the way, if it works for you, there's no errors :)
