I want to use manual axes information in an image. I tried axes image and edit axes after imshow. Both times failed to show the x or y axes. I am uploading the image. Please someone help.

Can you share any pictorial representation image (You can use any Image Editing tool)?

After calling imshow(), try this:
axis('on', 'image');
You can also set the default for axes visible on the Tool ribbon: Home/Preferences/Image Processing Toolbox/Axes Visible.
If you want the axes to be in custom units rather than in pixels, set the 'XData' and 'YData' properties to whatever numbers you want the first and last pixel to be in each direction. For example if you wanted the image to be 19 wide and 10 high, you could do this:
imshow(yourImage, 'XData', [0, 19], 'YData', [0, 10]);
The axes will show those numbers instead of the pixel values.
