I just delete my son picture a moment ago on my lg android cell phone and all I'm getting is people telling me i have to download a photo recovery. the only problem with that is it won't open when i download it to my phone. thee other one is i don't have a computer or lab top so how do i get my picture back from my cell phone. somebody please tell me.
If the phone is rooted you can download and install "DiskDigger" from PlayStore. Again, this will only work if the device is rooted.
If it's not, you'll need to get access to a PC and use a recovery program. There's a guide that you can read here on how to do it.
In the mean time, don't download or install anything else to the device. When you delete photos or files they aren't actually "erased." They're just removed from view, and the system will write new data over top of them.
