Do you have photshop ? if so follow this ...
Launch Photoshop and open the image you want to work on. To open an image from a file, from the "File" menu, click "Open." Select the folder you need, click on the file name and then click "Open."
Create a new canvas to work on by clicking on "File" and then "New." In the dialog box, adjust the width and height of the new canvas so that it's much bigger than the image file. Click on the down arrow next to "Background Contents" and select "Transparent" and then "OK."
Copy your original image to the new canvas. First, click on your image. Then, from the "Select" menu, click "All." Next, from the "Edit" menu, click "Copy." To paste, click on your new canvas, then from the "Edit" menu, click "Paste."
Select the "Filter" menu. Click on "Distort" and then "Shear." At the top of the dialog box, you'll see a thick black line in a grid. Drag the line to create the curves and bends you want. Photoshop shows you a preview of your work as you drag the line, so you can see how your curves affect your work.
Choose "OK" when you bend the image to your satisfaction. This will apply the curves to your image. Save your work by choosing "File" and then "Save As."
