vkDestroyImage

To destroy an image, call:

void vkDestroyImage(
    VkDevice device,
    VkImage image,
    const VkAllocationCallbacks* pAllocator);

device is the logical device that destroys the image.
image is the image to destroy.
pAllocator controls host memory allocation as described in the Memory Allocation chapter.

All submitted commands that refer to image, either directly or via a VkImageView, must have completed execution

If VkAllocationCallbacks were provided when image was created, a compatible set of callbacks must be provided here

If no VkAllocationCallbacks were provided when image was created, pAllocator must be NULL

image must not have been acquired from vkGetSwapchainImagesKHR

device must be a valid VkDevice handle

If image is not VK_NULL_HANDLE, image must be a valid VkImage handle

If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

If image is a valid handle, it must have been created, allocated, or retrieved from device
