First of all, even photos data, any data store in the CD, also will have possible data loss and cannot be read long long time later... it was because, when you burn the data to CD, it really depend on your CD quality, some of the CD mention that, the data can keep for 100 years (Kodxxxxx), but do you think after 100 years later... you still keep the CD? May be you already burn the CD data back to DVD disk, or Blu-ray disk few year later...
There have NO 100% sure has NO data loss, climate and your storage at good condition. This is NOT only for Photo data. If the data very important, you only can keep more than one copy and backup all at few year later...
Good Luck!!
