During image destroy, delete textures only if we have a GL context.

This is not right. If you're not removing and destroying the image here
resources will be kept around forever or until the GPU process is killed. You're
basically leaking GpuMemoryBuffers.

You need to Destroy and remove the image here.

Done.

Done.
