This GIMP (GNU) tutorial demonstrates how to slice a pineapple into a Photographic Collage. To work along, you are welcome to download the Start Image I am working with Here. Unzip the file and open the image onto GIMP’s workspace.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu, choose View then select a Zoom Tool from the subsequent drop-down list.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).
Launch GIMP & Organise Its Workspace & Palettes
Open your choice of Start Image onto GIMP’s workspace - File then Open - Ctrl then O.
Then create a New (Transparent) Image, and set the following Width and Height and Fill with Transparency attributes (File then New - Ctrl then N).
Ensure that your new Transparent Image is large enough to accommodate your sliced image. To see how large your Start Image is, from the top menu, choose Image and then choose Canvas Size.
Throughout this tutorial, you’ll be working between the Pineapple and the Transparent Images workspaces’.
Now, maximise the Transparent Image by clicking its top-right Maximise tab.
Then, (working on the Pineapple’s Workspace), from the left-side Toolbox, activate the Rectangle Select Tool.
And enter the following settings into the Toolbox.
Now, left-click and drag out a small Rectangular Selection Marquee over the top of the pineapple - as illustrated below.
And then from the top menu, choose Edit and then choose Cut.
Now, navigate to the Maximised Transparent Image’s Workspace. And from the top menu, choose Edit then choose Paste As and then choose New Layer.
Congratulations, you have just pasted your first pineapple slice onto the Transparent Image.
Whilst Copy and Pasting your Pineapple Slices, until the Pineapple has been completely sliced and pasted onto the Transparent Image; it’s important NOT to activate a different Tool.
Return to the Pineapple Image’s Workspace. And left-click and drag the Rectangular Selection Marquee so it’s positioned over the next sequential “pineapple slice” - as illustrated below.
Then from the top menu, choose Edit and then choose Cut.
Again, return to the Transparent Image’s Workspace. And from the top menu, choose Edit and the choose Paste As and then choose New Layer.
Congratulations, you have successfully Pasted the second Pineapple Slice onto the Transparent Image.
Now, working between both workspaces. Slice up (Cut) the remaining Pineapple, and Paste it onto the Transparent Image.
After you have completely sliced and pasted the Pineapple Image onto the Transparent Image, you are ready for the next step.
It’s safe to Close the “empty” Pineapple Image - File then Close.
Now is a good time to save your Layered Sliced Pineapple Image as a XCF File.
From the left-side Toolbox, activate the Move Tool. Then activate, and drag each pineapple slice to its final position, Rotating them to your liking, as necessary.
Drop Shadow Tip
Activate each Layer, one by one, and apply a Drop Shadow to them. My Tutorial Here demonstrates how to apply a Drop Shadow - Filters then Light and Shadow then Drop Shadow.
Activate each subsequent Slice Layer, (one at a time), and tap Ctrl then F to quickly reapply the same Drop Shadow.
Activate each Layer, one by one, and apply a Bevel to them. Filters then Decor and then Add Bevel.
Activate each subsequent Slice Layer (one at a time), and tap Ctrl then F to quickly reapply the same Bevel.

Fill Layer Tip
My Tutorial Here demonstrates how to create a Fill Layer and Fill it with either a Solid Colour, Pattern or a Gradient.
To create extra impact, apply a Sharpening Filter of your choice - Filters then Enhance.
My Tutorial Here demonstrates how to resize object/images.
From the top menu, choose Image and then choose Flatten Image. Congratulations, you have successfully sliced your Pineapple, and it’s ready to optimise and save.
Now you are more familiar with this technique, you can have lots of fun slicing personalised photographs or images.
