Get URL path for image from episerver blob file
Hi, can't you use the public URL to the thumbnail? Not sure what format this is "http://localhost:8000/episerver/f791355aa6334c92b5f370c5cfafd971/adc882777a04431baae83a2e05f3f02d.jpg", it looks like nothing our APIs would produce. You can access thumbnail properties by appending the property name to the URL:
private readonly IUrlResolver _urlResolver;
var thumbnailUrl = _urlResolver.GetUrl(imageContentReference) + "/thumbnail";This works for any thumbnail property your content type might have. 'Thumbnail' is the default thumbnail property available on ImageData.

If you have a content reference to the media, then it's easier to follow Johans suggestion.
However, if you only have access to the blob instance - have you tried using the blob.ID property? Can be used in one of the following ways:
Blob blob = ...;
var url = UrlResolver.Current.GetUrl(new UrlBuilder(blob.ID), ContextMode.Default);
// ... or in a Razor file ...
@Url.ContentUrl(new Url(blob.ID))
// ... and also explore ...
var absolutePath = blob.ID.AbsolutePath;

I don't think this code will work if e.g. the blobs are stored in Azure Blob Storage.
I'm creating a blob file using the following method in my code
Adding to Blob
Thumbnail = MediaToBlob(thumbMediaUrl, accessToken, ".jpg", blobFactory, qbankMedia, "text/html"); blobCache.Add(videoMediaUrl, qbankMedia.BinaryData);MediaToBlob Method
public Blob MediaToBlob(string mediaUrl, string accessToken, string extension, IBlobFactory blobFactory, IQBankEpiMedia qbankMedia, string mimeType, int maxLength = int.MaxValue) { var mediaStream = GetMediaStream(mediaUrl, accessToken, mimeType, maxLength); Blob blob = null; if (mediaStream != null) { blob = blobFactory.CreateBlob(qbankMedia.BinaryDataContainer, extension); using (var blobStream = blob.OpenWrite()) { byte[] buffer = new byte[64 * 1024]; int read; while ((read = mediaStream.Read(buffer, 0, buffer.Length)) > 0) blobStream.Write(buffer, 0, read); mediaStream.Flush(); mediaStream.Close(); } } return blob; }I Need to get a relative path to this Thumbnail object so that I can use it to render the image in site. I can use Thumbnail.ID.AbsoluteUri to get this :
epi.fx.blob://default/f791355aa6334c92b5f370c5cfafd971/adc882777a04431baae83a2e05f3f02d.jpginstead of that, I need something like this:
http://localhost:8000/episerver/f791355aa6334c92b5f370c5cfafd971/adc882777a04431baae83a2e05f3f02d.jpgCan anyone guide me to have something that I can use as normal Url for images?
