I get the same result when I browse directly to the link.
So, if OP links a malcious website we have a problem … (?).
Not really that huge of a problem. When making requests you also usually send a header which includes the user agent.
The program just logs how many times the image has been requested and it reads the user agent data. No Javascript is actually executed.
Well it might be possible to have a XSS somehow but I haven’t really done much research into this possibility.
In general it’s a pretty standard way of handling embedded images. Email does this too. That’s how you have these services that can check if someone read a mail
okay so I make a test here, with this : 
I believe this web page doesn’t load automatically.

Oh dangit, it’s simpler than I thought. So the only data being sent is…just whatever is sent in your average GET request.
Yes. It’s also a pretty standard way of serving images. A lot of Email clients do that too.
That’s also how these services that show you when a email is read work.
