Answer 1

If it is one of your server, you should figure out what is the pattern of your image file names, for example, x-y.jpeg, where x is from 1 to 100, and y is from 1 to 9. Then process with this code:
foreach (range(1, 100) as $x) {
foreach (range(1, 9) as $y) {
$html = get_data('http://mysite.info/screenshots/'.$x.'-'.$y.'.jpeg' );
}
}

You cannot use wildcards or similar approaches in http requests. Such a request has to query exactly one specific object, except if you have a processing logic in the server side.
In your example you use urls requesting a specific image file. Using that approach you request exactly one single and specific image. You'd have to make a single request for each possible name pattern to retrieve all available image files matching your desired pattern.
Another approach would be to not request a specific image in your http request, but a processing logic, typically a script on the server side. Such script can accept things like a wildcard pattern (or similar) and return matches, even multiple images at once. But this obviously means that you have control over that server system, can implement the logic on that system. So it has to be your system you query the images from.
