I've created a stack containing several hundred cards, each with a jpeg of a radiologic image. In order to test students, each x-ray is unlabeled with arrows. In order to provide a clue to the student, I've prepared a duplicate hidden picture on each card with the same picture, but with arrows pointing to key areas to look at. The duplicate picture is titled "arrows" and is set to be hidden, until the student clicks on a button titled "hint" which contains the script '"show image "arrows"'. In order to create the duplicate picture, I copied and immediately pasted the original picture on the same site on the card. I then opened the image editor and put in the arrows and updated the picture.
I recently phrased the question to the forum as to whether it was possible to minimize the stack size, since so many of the original pictures were resized right on the card. Apparently, just resizing the images and locking the size and position on the card does not reduce the size of the stack. So, Phil Davis suggested an excellent brief way to do this through the following script: on mouseUp -- first, prevent the image from expanding when reset set the lockLoc of img "myImage" to true -- reset the image's data put the imageData of img "myImage" into tData set the imageData of img "myImage" to tData end mouseUp In order to try this on the entire stack, I modified the script a bit (fortunately I made a backup stack first): repeat with x = 1 to the number of cards go to card x repeat with y = 1 to the number of images if there is an image y then put the imageData of img y into tData set the imageData of img y to tData end if end repeat end repeat This indeed did significantly reduce the stack size. However, all of the "arrows" pictures in the stack disappeared. They would no longer appear with the command 'show image "arrows"' or on turning on "Show Invisible Objects" from the view menu. The "arrows" pictures could not be found, but strangely they still were listed in the Application Browser. Does anyone have any suggestion as to how to account for this? The only thing I can think of is that the original pictures can be found in the Finder. The duplicated pictures, as always, cannot. Perhaps this has something to do with it. Thanks very much.
