I want to read in image files from my online database.
I would like to check my website to see if the file exists before attempting to load it into the workspace.
For Example I would like to do (simplified):
E = exist('http://www.mywebsite.com/images/1.png);
if E ~= 0
IMG = imread('http://www.mywebsite.com/images/1.png);
else
IMG = zeros(X,Y);
end
Thanks in Advance!

You could just use a try/catch block.
try
IMG = imread('http://www.mywebsite.com/images/1.png);
catch
IMG = zeros(X,Y);
end

you can use urlread also
[str,status] = urlread('http://www.mywebsite.com/images/1.png');
if status
IMG = imread('http://www.mywebsite.com/images/1.png');
else
disp('URL read of link was unsuccessful')
end
