Q: Since upgrading to IOS 7'photos taken on my iPhone are not transferring to the cloud. Sometimes a few will up load but then nothing for weeks. Anyone else had this problem

Since upgrading to IOS 7 the photographs I take on my iPhone 4S do not transfer to the cloud. Sometimes one or two of them transfer but then none for weeks. I have deleted photos from the cloud in case it is full but to no affect. I use my iPhone in conjunction with an iPad so this is driving me mad. Anyone else have this problem?
