Hi,
I'm trying to load and display an image using imshow().
im = im2double(imread('/MATLAB Drive/My Project/images/selfie.jpg'));
figure(), imshow(im);
The figure window comes up, but nothing is there. If I try to save the image using print I get a white image. I can look at the im variable, and it seems to have loaded properly. Help!

Use syntax:
imshow(im,[])
when im has non-integer format. Or just do this:
im = imread('/MATLAB Drive/My Project/images/selfie.jpg');
figure
imshow(im)

@Isabela Rodrigues what error message do you get? This works:
%Image
HeadCT = imread('circuit.tif');
imshow('circuit.tif'); % Or imshow(HeadCT);
which is essentially what you did.
If you have any more questions, then attach your image with the paperclip icon after you read this:

Any JPG file that can be read by imread() should be able to be displayed directly with imshow() or recast using im2double(). Either the image file isn't being read as expected, or there's something wrong with imshow() that I can't guess at.
You'll have to provide more information about the specifics. Do all images behave this way? Is it only certain images? If it's a certain image, attach it.
