Upload to Azure Blob Storage using Powershell

I needed to automate the process of uploading images to Azure blob storage recently, and found that using something like the excellent Azure Storage Explorer would not set the Content Type correctly (defaulting to “application/octetstream”). As such, here’s a little script to loop through a directory and do a basic check on extensions to set the content type for PNG or JPEG:

The magic is in Set-AzureStorageBlobContent.

Don’t forget to do the usual dance of calling the following!

These select your publish settings file, and set which subscription is the currently active one:

  • Import-AzurePublishSettingsFile
  • Set-AzureSubscription
  • Select-AzureSubscription


Actually, the Aug 2014 version of Azure Storage Explorer already sets the content type correctly upon upload. Oh well. Still a handy automation script though!
