I just bought an LG Optimus Slider last night and somehow when I connected it to my laptop to charge it, some of the photos on my laptop ended up on the phone. They aren't on the micro-SD card, yet they show up in the gallery. These are not photos I want just anyone picking up my phone to see. I cannot figure out how to remove them from the gallery. Plugging it in is not working because there's no file that shows up. I've tried touching and holding my finger on the photo, but nothing comes up that says 'delete photo'. Help! Update: I have finally managed to get a delete option to show up, but it disappears when I try to select photos to delete. If I keep my finger on a group of photos a delete option eventually shows up, but then I remove my finger to select the group of photos (green check mark) the delete option disappears.
