You probably will need to give more info to get help. But as I am just passing thru I'll take a stab at it. Use a file explorer to look at SD and sd-ext folders on phone. Often stuff is stored under dcim. I don't have a Samsung so can't be more specific. Good luck!
Well, I actually deleted everything on my dcim folder on accident. I thought I would make get rid of the stuff I didn't need and because I don't understand technology I deleted the most important file on my phone.
ALOHA welcome to the forum. at any time did u back up ur files to ur pc or perhaps to anapp like Astro file, before u deleted? if u didnt, u probably lost ur pictured
