A friend wants some of my images to use as wallpaper for his computer and I would like to help her. My question is how shall I proceed in Photoshop in making the images good for wallpaper but small enough so he cannot make large prints out of these images.
These are 35 mm slides scanned at scanned at 1300 dpi. the document size is
1.346 by 1.0 inch. I tried to reduce them to 72dpi however then they get so
small and when I enlarge them they look very pixilated. I must be doing something wrong so any help or direction will be very much appreciated.

Just open the image. Presuming the 1.5" is the width, and her screen is 1200 pixels wide: Take Image – Image Size. At the top where it says Width, type in 1200 (pixels) and under Resoution type in ’96’ and check the ‘resample image’ box and optimally choose ‘bicubic smooth’ from the dropdown menu next to it. Save it. Default file format for WindoZe desktops is BMP. Do that.

You can adjust the 1200 figure as you please to suit her actual desktop size. But you aren’t going to make it something she can’t print.

You just need to resize the image to fit his monitor, and this will depend on his display settings in his control panel. Right now, the image 1750 by 1300 pixels, right? (1.346 x 1300 and 1.0 x 1300).

Go to Image > Image Size and deselect "Resample Image." Change the resolution to 72.
Click OK

The image is now at 72 ppi and no loss has occurred. The image is still 1750 by 1300 pixels, just the resolution has been changed. Now all you need to do is change the size, to fit his monitor. If his screen resolution is 800 by 600, you can go back to Image > Image Size and reselect "resample image" making sure "constrain proportions" is also checked.

Change the height to 600 pixels. The width will automatically change to 808. Click OK. Now we just need to trim off the 8 extra pixels. You could leave these if you wanted to and the image wouldn’t suffer much. But to delete them we could use the Crop Tool. Enter the dimensions in the option bar at the top:
Width = 800 px
Height = 600 px
Resolution = 72

Drag your crop tool from a top corner diagonally to an opposite bottom corner to define the crop area. Press Enter.

Now what I would do at this point is grab the Type Tool and type your name and date in a corner or near the edge of the image, and a possible title or place. You can reduce the opacity of this Type Layer to allow some of the image to show through, but it would mark the image as "yours." Make it large enough to hinder further cropping, but small enough to not be a distraction.

Now go to File > Save for Web and save the image as a JPG. Give this copy to your friend.

If his resolution is different, just make the allowances in the appropriate places.

Thank you very much indeed for the suggestions and I think what I was doing wrong was changing all the values at once. Very kind of you to help.
