It's a simple issue. You created the CDR with the DRAG TO DISK feature of Roxio. This is not compatible with your DVD.
Try a New Data Disk (the name may change with version of Roxio so I leave it to you to sort that out) and then add these pictures to the "project" and then record the CDR and make the CDR "closed" or "final".
That usually will work.
I have put all my digital photo's on formatted CD-R discs using Easy CD Creator and copy and paste. They work perfectly on my computor. I now have a Cyberhome DVD player with progressive scan. The manuel states that it will play CD's with images in the jpg mode, all my photo's have the jpg extension after the name. The CD's will not play, what does happen is the red/green indicator light on the front rapidly blinks back and forth. Either the manuel is wrong (unlikely) or I have done something wrong (very likely), Please help. Thanks in advance, Tom837
