@Arcana @Moon to my surprise, I fully agree with ChatGPT on this one. If an image doesn't have alpha channel, it is opaque, so add_alpha implies adding transparency. The ":transparent" part could be the tricky part because some image formats and programs interpret the value as opacity (higher value is more opaque) and some interpret it as transparency (higher value is more transparent). So if this poll is a trick question or is highlighting bad code, that's where the trick might be.

The words "visible" and "invisible" are unclear in this context, so I'm assuming they mean "opaque" and "transparent".

I'm very surprised that I'm in the minority by choosing "This will make the image invisible".
