  Resize Images on Azure blob after uploading them

  Apr 03, 2018 08:37 PM|elshorbagy|LINK

  Hello,
  
  I'm uploading images using Web API to Azure Blob, I want to resize the uploaded image if the dimensions are greater than 900*900 and then create a thumbnail image.
  
  I created an Azure function using Azure templates but it is not firing when I upload an image or resize the image even when I run it manually. I don't know what is wrong with it,I'm a newbie still with Azure!! Is there a better way to do that with C# and Azure?
  
  Thanks

  Hi elshorbagy,

  According to your description, I couldn't directly find the reason why your azure function doesn't work.

  Could you please post the details error message about your azure function?

  Do you set the right blob path when you create the azure function?

  Besides, I suggest you could follow below tutorial.

  Hi,

  It seems the error is that you are trying to read a blob from the "images" location while it should be "images/blobName". I assume "images" is a container for your blobs ?

  Basically a "container" is likely a folder but you still have to tell which "file" (ie blob name) you want to retrieve.
