  12. // 01. to use hover over the image(container) to view a popup of the target image
  13. // 02. to zoom in/out use wheel up/down.
  14. // 03. click left mouse to lock popup this will make it move along with the mouse, click again to release (indicated by green border)
  15. // 04. while being locked"Y" the wheel up/down will act as scroll up/down
  16. // 05. double click will lock it on screen preventing it from being hidden
  17. // 06. hover below the image and click blue bar this will make a 3rd mode for wheel bottom, which will scroll next/previous image under an album
  18. // 07. while locked at screen (indicated by red outline) a single click with the blurred background will unblur it, only one popup per time, so the locked popup will prevent other popup to spawn
  19. // 08. double clicking on blurred background will de-spawn popup
  20. // 09. click on the corner to toggle scaling (blue) will retain current aspect ratio, double clicking will turn to 2nd mode for scaling (magenta) will not retain current aspect ratio
  21. // 10. return to original aspect ration via clicking on sides, if it's in an album to reset to aspect ratio on bottom side use double click
  22. // 11. you can now crop and save the image, just double click the top to initiate.
  23. // 12. to turn on/off hover at the bottom of the page
