Method to do on-the-fly image adjustment

[abfleishman]

Often camera trap images are not well exposed for the target animal. Being able to adjust the image brightness and contrast, (and maybe color?, sharpness etc) could greatly aid users in being able to annotate poorly exposed images.

@abfleishman totally agree.

I looked into this a little while back, and TrapTagger uses Leaflet somehow to do this, but I think this Konva might be a potential route too.

Added to the roadmap :)

Might be a pure CSS approach too: https://stackoverflow.com/questions/2644399/brightening-an-image-using-styles-or-javascript
