I just found some useful walk trough here and make sure to read follow-up that improves the save process and used image

We did it by saving the images on disk (not in a DB) - like this:

Upload image:

• Write a Domain Service with an operation like void UploadJPGImage(string uniqueName, byte[] jpgBytes). This needs to be marked with the attribute for ClientAccess. The (server-side) implementation saves the image on the disk.
• for the uniqueName, we generate a GUID client-side

Download image:

• HTTP Handler - write an HTTP handler for downloading the image using a URL containing the unique name parameter passed by the client when uploading the image
• Or, one could write a Domain Service operation, like byte[] DownloadJPGImage(string uniqueName)
