Thanks for responding. I'm not sure if I totally understand your question, but I'll try to clarify some things. Each record represents an insect species, for each species I have up to 10 photographs associated with it. Each photo is in two sizes, a thumbnail and full-size. So each species record has container fields for the thumbnails and container fields for the full-size photos. To save repetition and numerous layouts I created a thumbnails layout and a full-size layout. The thumbnails layout has all of the thumbnail container fields on it, so you can view them all at once. However, when you click on a thumbnail, its script takes you to the full-size layout, which only has one field on it, a global "LargeGraphic" field. The field is global so that it can be easily cleared and a new full-size photo can be pasted in depending upon which thumbnail you choose. When I burn the CD, this clearing and pasting feature disappears because you can no longer "write" to the CD. I am wondering how others have used thumbnails and if they have run into this CD problem. Thanks.
