The photos should be stored in your C:\Users\ \Pictures directory. Using File Explorer, go to that directory to check. If they're there, then you can safely delete that application 
I have two photo programs on my laptop.  The original one from Dell and one additional one. I want to remove the Dell installed one. I do not like it at all.  If I remove that does that affect the other program and my photos there?  Also, where are my photos primary stored in an Inspiron laptop?   Thank you.
