maybe simple question but i am stuck for like 2 days,
i have azure blob storage to store images for MVC application running on AppService and i need best way to store images for different galeries

i have definition in database like ImageName | Galery_Id for example
and i will run some ajax to get data from database by Galery_Id

now i have all image names (prox 150-250 images per Galery)
but i need best and fastest way to render then on frontend and have like static function on backend that will retrive them 1 by 1 from azure blob seems little bit slow and so complicated

public static string GetImagesFromBlob(string name)
{
    BlobServiceClient blobServiceClient = new BlobServiceClient("");

    blobContainer = blobServiceClient.GetBlobContainerClient(blobContainerName);
    blobContainer.CreateIfNotExistsAsync(PublicAccessType.Blob);

    List<Uri> allBlobs = new List<Uri>();
    foreach (BlobItem blob in blobContainer.GetBlobs())
    {
        if (blob.Properties.BlobType == BlobType.Block)
            allBlobs.Add(blobContainer.GetBlobClient(blob.Name).Uri);
    }
    return "";

}

Actually i dont want to use SAS keys

is there any option to use already authenticated user on app and use image tag without SAS key?
or any other idea? i want all things in Azure
Thx a lot
