Help with pretty easy script

Thank you so much for the help man, i really appreciate it.
How did you crop the gems using the link you sent me? When I try they are resulting in black and white images

Tried to crop and add the black and white golden images and still it cant find them within screenshots.
Can you help me with the cropping? I think i fail with this, tried dozens of time to do it well T_T
If I send you the screenshots of the 10 gems can you crop them for me? I know I'm asking for too much, thank you for your time and patience mate, really appreciate it.

I can send you some screenshots of the gems which you can crop from, I'm a high level and it still is very hard to find them
And its 1080 x 1920, I have oneplus3

Will do and update, thanks <3
And is there a way to crop the images without the black and white?

How do I crop it with PC?
And I need to change the scriptDimension to 1920?

I cropped all of the images correctly and it does manage to find them good and great (see in the end of the video)
But there are 2 problems:
-The getChestRegion function is checking the previous chest instead of the current one (see in the start of the video)
-It's pretty slow
So in order to fix the first problem I need to delay the calling of the getChestRegion so the skipping dungeon click will be done and it won't pick the same chest consecutively, how do I do that?
And do you have any idea how to make it faster?
And just from curiousity, is there a way to make a sound notification?

Thanks for the help man, you're seriously a pro. Can I donate you somehow? 

btw using img_r()

your code should be like this on test mode

to see the final result(without highlight, more speed) change this line to false
