To bring your pictures together in Photoshop:

As usual - save originals and make duplicate files (so that you can work on duplicates without damaging originals).

1. Decide which is going to be your background and which the overlay.  Remember the background is the starting point and other pictures go into it.
2. Use the move tool (top right 'tool palette' icon). Click on to the overlay picture and drag it on top of your background picture. This now appears in the background layer palette as 'Layer 1'.  You can name this layer by clicking on the layer palette where it says 'layer 1'.
3. If you want, you can see both pictures at once.  To do this, in the 'Layer Palette', change the 'Opacity' scale to a lower percentage (making sure that 'Layer 1' is selected). Now you will be able to see the background layer behind as well as the overlay.
4. Creating a Layer Mask and using 'reveal all' (or 'hide all' - see 7.). This helps to improve your accuracy but remember whichever way you do this the job is fiddly! Select the top layer 'Layer 1' go to -
   layer - layer mask - reveal all.
   
5. Reveal all shows all the overlay. You can alter the opacity in the Layers palette if this helps but it is easier to see what you are doing at 100%. To get rid of what you don't want use the paintbrushes. First, check that the colours (at the bottom of the 'tool palette') are black and white - you can switch between these using 'x' on the keyboard (to add or subtract from the picture) or click the arrow next to the box.
6. Click on paint brush and choose an appropriate size from the tool bar. Make sure the layer box in the Layer palette is highlighted (click on it). Then paint away with the brush - getting rid of the overlay that you don't want. If you take away something you want press 'x' on the keyboard and then paint it back in.
   
7. and using 'hide all'. At number 4 above you can click on 'hide all' instead in which case the overlay is hidden and you paint it back in using a paintbrush and the black and white colours at the bottom of the tool palette.
8. When you are finished merge the layers together.  You will not be able to work on them after you have merged so make sure you are ready.  Go to the Layers palette, merge layers, save as a jpg.
9. To get this on screen (on your blog or else where) make another duplicate file (this time put 'screen' in the title).  Go to image file and reduce the size to about 600 ppi as the maximum length or width at 72 resolution.

Don't forget that to use this image (rather than work on it) make a duplicate, go to the Layers window and flatten Layers then save as a jpg. Again, if you are going to present this on screen go to image size and reduce it to 72 dpi.
