This is a rather specific, yet fundamental question. I am creating a diagnostic photograph CD using FM 5.0 on a Windows platform. What is the best (i.e. file size, speed, etc.) way to go from viewing thumbnails, to viewing full-size photos? Currently, I have a Thumbnails layout and a Full-size layout composed of a global "LargeGraphic" container field. I have scripted the thumbnails so that its full-size counterpart will be pasted into the global "LargeGraphic" field and they will view it in the Full-size layout. The problem is when I burn my CD, the global "LargeGraphic" field can not be rewrited to, therefore, the photos don't change. Is there anyway I can solve this problem other than creating personalized Full-size layout for each of my thumbnails?

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.

Why don't you use the GetURL function in filemaker and leave the larger images in a folder on cd where you can go to a local file and launch the larger images via a browser.

I hear ya. To understand better, what are your reasons for not wanting to have all of the large images as individual records (rather than a global)?
