How to resize images in one layer to be to scale for an image in another layer?

[iggy73]

Hi everyone - I'm a newbie here and have spent a non-trivial amount of time looking for the answer to my problem with no luck. I'm not saying it isn't already out there... just that I haven't found it. So... this post is as a last reort for me - I look forward to the community's help!

I would like to make a composite image with source images making up the various layers (so I can work my magic on each layer indepent of the others). The problem I have is that not all of the images I'm using are to the right scale. What I want to do is resize those layers that are too big. Here's an example...

Let's say I have 5 pictures that I want to use to make one composite image from. The main background layer will be made from an image that is, say 800x600.

Another picture (let's call this subject 1) is 600x600 and is already at the right scale if I cut out the portion I want to keep and lay it on top of the background layer.

Yet another picture (subject 2) is huge (think 2000x2000). I would like to cut out the portion I would like to use and drop it in as a new layer and then obviously re-size it down to the correct scale. I'd prefer to do this directly in the composite image I'm making on its own layer to ensure I get the size right (and without manipulating the image guess-work style before I cut/paste it in).

And so on...

I've found ways to make the canvas bigger (not what I want to do)... but not anything on how to resize the images on individual layers without impacting the other layers. Is there a way to do this?

THANKS IN ADVANCE EVERYONE!

The main background layer will be made from an image that is, say 800x600.

Import this layer first.

Next, import another image.

Layers > Import from File...

If it is oversize, the canvas will expand to accommodate it. Let it do so.

Make a Rectangle selection around the part of that layer that you want to use.

Copy/paste into a new layer.

Ctrl + C

Ctrl + Shift + V

Delete the original oversize layer that you have just copy/pasted from.

The selection you copy/pasted should still be selected,

and the Move Selected Pixels tool will be active.

Re-size using the Move Selected Pixels tool on a corner adjusting nub.

Repeat for each additional layer.

Awesome - THANKS! This worked for me and was very easy to do and follow. Now I'll spend some quality time with a few tuts...
