Cant view pictures on iphone PLEASE HELP :(

For some reason whenever i go into my messages app and i press on a picutre to view a gray screen that says 'JPEG Iamge" comes up. I recently downloaded biteSMS on my jailbroken ios6 iPhone 4 and this started to happen whenever i try to open a picture in my messages... i can save them to my camera roll but i cant view them in the app itself...ive tried putting my phone in safe mode but it still happens :/
