images without a red shape

[hb0nd]

This is quite confusing - there is no red shape so it could be assumed that you should swipe right, but it presumably means to swipe left.

Ideally, blank images shouldn't be shown

Thanks for the feedback @hb0nd !
We had a few people commenting on this and we realise that the logic behind the 'not showing the red shape` is fallacious. This comes from the generation of TN images as by our current framework, we have tried to explain this in the README page.
Though, we are going to address this in issue #7, feel free to contribute if you like!
