One of the prompts I got today was I had filled all nearly 100 photos that uploaded to Social Club, some of this was done in error, and the prompt was to delete them you go into the pause menu, where Gallery is, all I can see is option to retitle a shot via console/controller. Perhaps there's more options from a computer at SC website, I haven't checked, but isn't it odd that the game is saying you can do it from within the game? I think there's an error here, but I wonder if you guys ran into the same issue.
We had a thread about Selfies and the like, I put in a link to my photo gallery, it's maxed out presently, so if you get a chance and found that, look at em before I delete what's there to take some more! haha
