Load up the phone via usb, and search for the files, access them and take off the read only attribute via properties.
If you can't find them then load up the SD card and make sure you have the View Hidden Folders option selected in the search feature [if you're using Windows]
On your Storm go to m.crackberry.com which will take you to the mobile site, then go to the Free Storm app Directory and it should be listed with the B's.
This happened to me with one pic. When I went to try to delete it it asked me if I wanted to delete read only file and I clicked yes. Then it looked like a corrupt icon and I kept trying to delete and kept getting do you want to delete read only file. I did a battery pull and the file was gone. So you might want to try that.
