How do i zero down 'pictures,videos' used up memory?

So i have 1.69GB total space and 418MB Available space (opened through settings then storage)
It shows "Pictures,Videos" have 2.43GB used up space!!!!!!
I opened the "Pictures,videos' clicked "Gallery".
deleted all the photos I have.. which was only (5)!!!!
and i have no videos taken with my phone.
I deleted every photo but the available space is still 418GB..
I restarted my phone but the 'Pictures,Videos' still has 2.4GB . I did this so many times. I even connected my phone and tried to delete it from there but it still didn't change a thing. How do I fix this problem? Is there a way i could even see what's making my 'pictures,videos' have 2+GB ?
