We have found many problems with running convert many pictures using v15.x (1,2,and 3).
Make sure as others have said that 1. Quick time enabled on server 2. Quick time installed- 3. check to see if picture compressed and if so uncompress first 4 Run on client not server. 5. Also I would not go to PNG, we have found that when converting to PNG pictures get huge, what was 1.2 meg as a pict in 4D can become 20 meg as a png 6. Another option is to print to pdf and then use acrobat professional or some other tool to convert to jpeg and any other format of you choice. Doing this means you will have to name files and then re-import same 7. You might also try write picture file and then read it and convert form there FYI we have over 500,000 pictures that we had to convert Regards Chuck ------------------------------------------------------------------------------------------------ Chuck Miller Voice: (617) 739-0306 Informed Solutions, Inc.
