 Allocating memory for an image works in exactly the same way as allocating
 memory for a buffer. Use `vkGetImageMemoryRequirements` instead of
 `vkGetBufferMemoryRequirements`, and use `vkBindImageMemory` instead of
-`vkBindBufferMemory`. Remember that we need the memory to be host visible to be
-able to use `vkMapMemory`, so you should specify that property when looking for
-the right memory type.

 This function is already getting quite large and there'll be a need to create
 more images in later chapters, so we should abstract image creation into a
