Merging separate images keeps you from recreating them in PaintShop Pro. You can use parts of an image inside another image to create a different scenery or the entire image. PaintShop Pro uses the paste as new layer option to copy contents of another image into a different image. By saving the merged image as a new image file, you can preserve the original files in case you need them in the future.
Open the two images you want to merge in PaintShop Pro.
Go to the first image and choose "Selections" and "Select All" from the menu or press "Ctrl"+"A" to select the entire image. To select a portion of the image alone, select the "Freehand Selection" tool from the toolbox and use your mouse to draw a selection around the area you want to keep.
Press Ctrl"+"C" on your keyboard to copy the contents of the canvas. Close the first image file.
Go to the second image file where the copied image goes.
Select "Edit," "Paste" and "As New Layer" from the menu or press Ctrl"+"L."
Drag the added image where you want it to go on the canvas.
Select "Layers," "Merge" and "Merge All (Flatten)" from the menu.
Select "File" and "Save As" from the menu to open the "Save As" dialogue box. To save the new file without modifying the original image, rename the file under the "File name" text field and click "Save."
