The fourth photograph is the cause and is either corrupt or located in a faulty area on the disc. Open the CD with file manager and copy all the other photographs on to your PC hard drive. At this step you might discover other, later photographs cause the same problem.Try to copy the faulty photo(s) into the same area on the PC and if they copy ok then you can then transfer the lot out to a new CD. If it fails to copy then you can transfer everything but the faulty ones out to a new CD.
There is any amount of software available, most of it for free, that can recover them (or so they distributers claim). Google "Recover corrupt photographs" to get a list.
