Articles > Photo Editing With GIMP
This tutorial will cover
Get started
Start by downloading GIMP from gimp-win.sourceforge.net. Once you’ve downloaded the program, open and install it.
Once you’ve installed the program, open it from the Programs menu on your Windows Start Menu.
Open your image
To open an image, click the "File" menu, then click "Open". Browse your computer for the image you want to edit, then double click to open it.
Rotating an image
Rotating an image is very simple. Click the "Image" menu, "Transform", then click "Rotate 90° clockwise", "Rotate 90° counter-clockwise" or "Rotate 180°".
Flipping an image
Flipping an image is also very simple. From the "Image" menu, click either "Flip Horizontally" or "Flip Vertically".
Red-eye removal
To remove red-eye from your photos of people, choose the "Rectangle Select" tool, then drag a box over the eyes.
Next, click the "Filters" menu, then "Enhance", then "Red Eye Removal".
Adjust the "Threshold" setting until the red-eye has been removed. A higher threshold level offers better red-eye reduction, but might affect the colour of other parts of the image.
When you are happy with the results, click "OK" to make the changes to your image.
Cropping images
If you want to crop your image and chop unwanted parts from the edges, select the "Rectangle Select" tool again. Drag a box over the parts of the image you want to keep.
To crop your image to the selected area, click the "Image" menu then click "Crop to Selection".
The image will now be cropped to the size of the area you selected.
Re-sizing images
Before you upload your photos to the Internet, I highly recommend you re-size them first. Smaller images take a lot less time to upload, saving you from sitting around twiddling your thumbs.
To resize your image, click the "Image" menu, then click "Scale Image...".
I would personally recommend that you resize your images to a maximum of 800 pixels wide and 600 pixels tall for landscape images, and 600 pixels wide by 800 pixels tall for portrait images.
Click "Scale" to make the re-sizing changes to your image.
