This has been bothering me for some time now, as I often make bug reports where I want to provide a before and after set of images for when the bug occurs. For example, showing that Cloudkill damage is reduced by the Earth Savant PrE:

Without the PrE:


And with the PrE:


While I suppose I could merge the images together, I would lose a fair bit of information if I attempt to make both viewable at once (for example, in these cropped images one can't see that my equipped items are consistent between the tests). As such, is there any way to attach multiple files to a bug report, or should I simply merge images when submitting "before-and-after" bugs?
