example If key of image is ff8081815848207b01584832ea1d012c_76516_original

then you have to access image like image="ff8081815848207b01584832ea1d012c"

I suggest that you read the documentation for the String class. – Code-Apprentice Jan 18 '18 at 19:38

`str.substring(0, str.indexOf("_"))` also does the trick – Juan Carlos Mendoza Jan 18 '18 at 19:38
Use: String.split(...)[0]. See the documentation for split. – Adi Jan 18 '18 at 20:46
