add blank area to right-hand side of image
I wanted to create desktop background image; that would be black at the right-hand side so the text that the operating system puts on the screen can be read;

ideally I would reduce the size of the image I want to use;

then put that image at the top-left of the photo; and I guess perhaps have an underlying black image;

once I get a pointer to things, I can get them moving; and gimp has always been there without me using it much;

if some very kind and patient soul could give me pointers, to get this done; it would be much appreciated; there is wonderful depth of wisdom in the readmes but a few quick pointers would be great.

RE: add blank area to right-hand side of image
I'm not kind at all, but perhaps I can give a few ideas...

You can always select Image -> Canvas Size to enlarge the canvas. I would always select "Resize All Layers" or "Resize Image-sized Layers". I think it will always fill the new area with the background colour, well, sometimes it does that, otherwise you get a transparent border that you need to fill with something.

Personally, I always use layers if I want to copy anything anywhere. Working with selections doesn't seem very doable. So, when you paste something into your image, you paste it as a new layer. Then you can move the new layer around by pressing M, but it is sometimes hard because you have to put your pointer on some visible pixels or something of the kind or it will grab the underlying layer. You can always add new layers for example filled with a black. In the layers dialog you can drag-drop layers around so as to change the order in which they get rendered. You would want that black layer to be at the bottom of the stack.

If you are satisfied with your layers and the placement of your individual smaller layers (such as that picture you want to put on your background) you can simply make sure all of them are visible and then you can export as PNG. You can also merge the layers together if you are satisfied enough and you want to fix it in stone.

Resizing the image is called "Scaling". It is not nearly as good as what IrfanView can do. But in my experience IrfanView messes up (messed up) PNG files with alpha values. So I use GIMP to resize PNGs now. You can also scale a layer, which means that everything you copy and paste, you can subsequently resize.

Using the Scale Tool makes it easier to resize a layer in a visual way.
