Load our texture after initializing Vulkan loader (for example after `ImGui_ImplVulkan_Init()`):

Now that we have an Vulkan texture and its dimensions, we can display it in our main loop:
```cpp
ImGui::Begin("Vulkan Texture Text");
ImGui::Text("pointer = %p", my_image_texture.DS);
ImGui::Text("size = %d x %d", my_image_texture.Width, my_image_texture.Height);
ImGui::Image((ImTextureID)my_image_texture.DS, ImVec2(my_image_texture.Width, my_image_texture.Height));
ImGui::Text("pointer = %p", my_texture.DS);
ImGui::Text("size = %d x %d", my_texture.Width, my_texture.Height);
ImGui::Image((ImTextureID)my_texture.DS, ImVec2(my_texture.Width, my_texture.Height));
ImGui::End();
```
In the cleanup stage remember to call the RemoveTexture function to avoid leaks, and angry Vulkan Validation Layers! Call it before `ImGui_ImplVulkan_Shutdown()`
```cpp
RemoveTexture(&my_image_texture);
RemoveTexture(&my_texture);
```
