put 2 scans over each other

i have made "in illo tempore" several electronic devices for which i made prints
so i made a copper layout for making the print, and a parts layout for that print, and scanned these on my scanner
now i want these on my PC, and for easy working, and finding parts, i'm looking for any software so i can put each over the other on my PC, just like the original documents, made on transparant paper, aka tracing paper

preferably free, but paid versions are welcome too

What photo editor do you have Nobus?
could you drop your two images over here so I can just do it then show how I did it and if they are suitable to overlay.
If the top image is has too many colours it will not transfer ontop it will just block out the bottom.
If the top layer has pieces you can use the magic wand to put a dotted line around those parts and copy that out paste as a transparent layer on top of the copper base.
 take your copper image and add it to your image editor, then add your parts layout, click on the parts layout image and then edit copy go over to the copper image click on the top edge and then rightclick it paste as transparent position it and then flatten layers
 I use Paintshop pro but photoshop should be similar.

>>  What photo editor do you have Nobus?  <<  Paint
here the 2 pics as example - both in 1 picture; but you can separate them - right?rcyou need to flip the lower one  in order to get it correct for putting it over the other one

the youtube is NOT what i need, nor is the gimp youtube the correct solution
Nobus, in order to put the diagram circute part over the  base I would have to lift the actual circute off the white background and make it  transparent.
 here is the one at the bottom >mirrored  transparent png, do you want png or jpeg?

Over layered it looks like this, I can move it around to align but didn't know where it actually sits against the copper board, as you see it is not like tracing paper.
over layeredWere you able to print it onto a transparent sheet like a clear plastic that'd work. You could then print out the base onto normal paper and put the clear sheet over the top

merete, the overlayered one is what i need, only the  copper should be in very light gray, so i can see the parts clearly
i assume we're nearly there?
Nobus will you accept the transparent parts I have already posted just save it it is png.
Base greyed, is this light enough? Anymore the letters disappear, the red disappeared so added it back in
nobusAuthor Commented:
merete, the above stays in black, the Copper part in light grey in the over layered you posted
The names are a bit confusing Nobus

Merete, how did you get the "better quality" view?
that's what i want !
Very Good Nobus glad you like it.
I enjoy doing photo restoration and with some tricks I taught myself and ingenuity I can do wonders with simple tools.
I use a combination of tools from my two versions of Paintshop pro Ultimate and Nero image editor.
 in Nero image editor adjusted the exposure and and then sharpen it save it
Load it back into my paintshop pro and using the selection tool manually put a line or circle or vertical line horizontal dotted line around specific areas I clone two colour for swatches and bucket fill each segment where the dotted line is using left for white right for that greenish colour
Using the two images side by side I copy the red text from old to the other and put it over the top, then while dots on I go to adjust colour and brightness of each letter. Preview them and when it looks good ok it.
I had a hand writing font so just cut out your R C Generator and using Text tool replaced yours since the Font matched but was nicer.
I've been working onit a bit more getting rid of the jaggered edges. A bit time consuming but fun to do.
load the two I have done into the browser then you flick between them and see the differences before after before after lol
You will see the slight adjustments I have done.

nobusAuthor Commented:
what version you have? and can the copper still be made a shade lighter ?
Paintshop pro 7 and 9. I found them the best, believe or not Power point has a lot exellent tools for image adjustments and can be copied directly from PP to to my paintshop pro and back.
Paint Net also excellent and free
If I adjust the grey lighter it can effect the entire piece but will give it a try.
Here's how it looks on Nero Editor I put it on split view
EE seems to be experiencing a good deal of lag uploading images.
