Hi,
My question is related to this example - https://www.mathworks.com/help/thingspeak/create-heatmap-overlay-image.html
It used an image stored in the web load it using the following command
picture = imread('https://www.mathworks.com/help/examples/thingspeak/win64/CreateHeatmapOverlayImageTSExample_02.png');
What is the most convenient way to host a custom image to use the imread() command. Can anyone explain it with steps.

It is possible to imread() a photo from Google Photos. However, the way to get the correct URL is obscure; the test I just did, the secret URL was over 800 characters of pretty random characters like P8PeurrnqmOMvBwVWkia-jeJQL6HPYz8boUvfvQ3GE

You can upload your files into your MATLAB Drive for sharing. It will require the user to log in to MATLAB Drive to access it. MATLAB can also save files into DropBox and read file out of DropBox programmatically using a dropbox token.
If you are looking for an alternative only for images - one that does not require a login, there are many options out there.

I've used Imgur in the past successfully. The key there is to post the image, then right click on the image in the browser and select "copy image url" and use the image url in MATLAB. See:
img = imread('https://i.imgur.com/IEkjCYz.jpg');
imshow(img);
