Showing One file for Multiple Posts

Hi,

Question 01:
Please take a look at this image:

Im using your free plugin in my wordpress based classified site. As you can see it is showing the same image for all ads. When I checked I noticed all the images have same name.
This is the 2nd time it happened. First time when it happened I turned on “Copy HiDPI (@2x) Images” option.
Now I turned on “Object Versioning”. Will this fix the problem?
Is it a bug?

Question 02:
I noticed you released the PRO version recently. Will you still offer updates, bug fixes, support for free version?

Thanks
