Thanks, Scott    Report

Does this solve your problem? Thanks, Ali Abo Al-Rob LEADTOOLS Technical Support    Report

I think I know what you mean. I wasn't sure what your last sentence "By setting the Width and Height" means, however. One thing I'm not sure about, is how to get multiple files in my search string.  The features in my database can have 0 or more pictures associated with them.  So, if my feature has two files, one named 40-04-01.jpg and one named 35-09-B4.jpg, how do I create a seach string that works?  I tried "40-04-01.jpg, 35-09-B4.jpg" and "40-04-01.jpg; 35-09-B4.jpg" but neither worked.  Any suggestions would be most welcome.

You should use the method below if you have specific files you want thumbnails for. As for the width and height, this is up to you. Whatever size you would like your thumbnails to be, you would specify it here.
