Having problems with creating image cache with Intervention \ Image - laravel

Question

So heres my code
public static function getImageThumb($link) {
$domain = substr(Request::root(), 7);
if(starts_with(Request::root(), 'http://')) {
$domain = substr(Request::root(), 7);
}
$link = $domain.$link; // This is prety much something like this domain.name/uploads/image/13_0.jpeg
$img = Image::cache(function ($image) use ($link) {
return $image->make($link)->resize(230, 140);
}, 5, true);
return $img;
}
And it gives me this:
Intervention \ Image \ Exception \ NotReadableException
Image source not readable
I dont really know whats wrong here..
Thanks for help!
EDIT-------------------------
I fixed it like this:
public static function getImageThumb($link) {
$link = trim($link, '/');
$img = Image::cache(function ($image) use ($link) {
return $image->make($link)->resize(230, 140);
}, 5, true);
return $img;
}
But how do i get the link to img now? So i can place it in src for img tag.

If you're going to use a URL as the source parameter for the make method, make sure it includes the scheme as well, or it will consider it to be a local file path. So get rid of the part where you strip the http:// from the URL, just use:
public static function getImageThumb($link)
{
$link = Request::root() . $link;
$img = Image::cache(function ($image) use ($link) {
return $image->make($link)->resize(230, 140);
}, 5, true);
return $img;
}
Also, since the image not from a remote domain, it makes more sense to just read it from the filesystem, instead of making a HTTP request for it:
public static function getImageThumb($link)
{
$path = public_path() . $link;
$img = Image::cache(function ($image) use ($path) {
return $image->make($path)->resize(230, 140);
}, 5, true);
return $img;
}
To return the cached version of a image, you have to have a dedicated route that retrieves the resized image. Something like this should do:
Route::get('/images/{link}', function ($link)
{
// Repo will be the class implementing your getImageThumb method
$img = Repo::getImageThumb($link);
// This makes sure the HTTP response contains the necessary image headers
return $img->response();
});
Now in your blade Blade template file you generate the URL like so:
<img src="{{ asset('/images/' . $link) }}">
By prepending /images to the actual link path you're hitting the route that is going to use the image cache if it is available. So your links would now look like this:
http://domain.name/images/uploads/image/13_0.jpeg
instead of
http://domain.name/uploads/image/13_0.jpeg
Of course you can use anything you like as the path prefix, not necessarily /images.
