You can rotate an image from horizontal to vertical to change its appearance or to create a new image.
When you take a photograph or save one from the Internet to your computer, you may want to edit it to improve its quality or change its overall appearance. If you accidentally take a photograph sideways or horizontal, you may want to rotate it vertically before posting it to image sharing sites or saving it in your collection.
Instructions
Microsoft Paint
1. Open Paint and click "Open" to open your image that you want to rotate.
2. Click "Rotate" from the main toolbar.
3. Click 90 degrees either right or left to make a photograph vertical from a horizontal position.
Gimp
4. Open Gimp and click "Tools" from the image menu bar after you open your image.
5. Click "Transform Tools," then click "Rotate."
6. Click either forward or backward to rotate the image forward or backward, depending on which direction it is facing. If you hold "Ctrl" while you are rotating the image, it will rotate in even 15 degree increments.
Picasa
7. Open your image in Picasa.
8. Click either the "rotate clockwise" or "rotate counter-clockwise" button from the menu bar. The image for each button is an arrow pointing in either direction.
9. Press "Ctrl," "Shift" and "V" to automatically rotate your image to vertical from horizontal.
