Answer 1

i'm pretty late to the party
but i got a few bones to pick with this solution provided.. so here it goes:
you mention you have different front and back configurations
so you are serving different folders for yii.com/:80 and yii.com/:81 respectively /frontend/web and /backend/web.
keeping this in mind,
no amount of aliases can make content of one of them available to the other.
the yii-advanced-app has #frontend and #backend aliases defined in common/config/bootstrap
Yii::setAlias('#common', dirname(__DIR__));
Yii::setAlias('#frontend', dirname(dirname(__DIR__)) . '/frontend');
Yii::setAlias('#backend', dirname(dirname(__DIR__)) . '/backend');
Yii::setAlias('#console', dirname(dirname(__DIR__)) . '/console');
DO NOT CHANGE THESE unless you know very well what you're doing.
Yii is using these aliases to autoload classes defined under these namespaces common, frontend, backend and console. this exact thing is causing the ridiculous chain of "errors occurring while handling other errors"
more details on Yii autloading documentaion
you can simply share content of these folders by creating a symlink from frontend/web/uploads to backend/web/uploads.
your webserver config (or .htaccess) will require the +FollowSymLinks option
Yii can manage this if you add a few lines to the environments/index.php file
'Development' => [
// .. other options
'setWritable' => [
// .. leave the default stuff there
'frontend/web/uploads',
],
'createSymlink' => [
// link => real folder
'backend/web/uploads' => 'frontend/web/uploads',
]
],
'Production' => [
// ..
'setWritable' => [
// ..
'frontend/web/uploads',
],
'createSymlink' => [
// link => real folder
'backend/web/uploads' => 'frontend/web/uploads',
]
],
and then run the init command again, just like in the installation guide (you do have to option to not overwrite local config files)
if you are running under windows, this might now ask you for elevated privileges
php init
or if you chose to make the symlinks manually you can try this quick guide

Answer 2

you can try this solution :
Yii::setAlias('#frontend', 'http://frontend.sample.dev');
Yii::setAlias('#backend', 'http://backend.sample.dev');
and if you upload files in backend set the src parameter of image to
Yii::getAlias('#backend/path/to/your/image/file');
and if you save your files in frontend replace #backend with #frontend

Answer 3

create this function in components folder
namespace common\components;
use Yii;
class Helper extends \yii\web\Request {
public static function getFrontendUrl($path) {
$frontUrl = str_replace('/adminpanel', '', $path);
return $frontUrl;
}
}
and use in backend :
$path \common\components\Helper::getFrontendUrl(Yii::$app->request->baseUrl).$img;
notic: in frontend You do not need
