-A managed image resource can be created from a generalized virtual machine (VM) that is stored as either a managed disk or an unmanaged disk in a storage account.

+Managed images are helpful in development and test environments where you need a consistent baseline VM. A managed image resource can be created from a generalized virtual machine (VM) that is stored as either a managed disk or an unmanaged disk in a storage account. The image can then be used to create multiple VMs. For information on how managed images are billed, see [Managed Disks pricing](https://azure.microsoft.com/pricing/details/managed-disks/). 
 
 One managed image supports up to 20 simultaneous deployments. Attempting to create more than 20 VMs concurrently, from the same managed image, may result in provisioning timeouts due to the storage performance limitations of a single VHD. To create more than 20 VMs concurrently, use an [Azure Compute Gallery](../shared-image-galleries.md) (formerly known as Shared Image Gallery) image configured with 1 replica for every 20 concurrent VM deployments.
 
 ## Prerequisites
 
 You need a [generalized](../generalize.md) VM in order to create an image.

 Creating an image directly from the VM ensures that the image includes all of the disks associated with the VM, including the OS disk and any data disks. This example shows how to create a managed image from a VM that uses managed disks.

 To create a managed image from a VM that doesn't use managed disks, you need the URI of the OS VHD in the storage account, in the following format: https://*mystorageaccount*.blob.core.windows.net/*vhdcontainer*/*vhdfilename.vhd*. In this example, the VHD is in *mystorageaccount*, in a container named *vhdcontainer*, and the VHD filename is *vhdfilename.vhd*.
