I used WinRAR to create the zip file.
Here another one but this time I used Windows Built in Zip tool to create it (Compressed (zipped) folde)
Hope this one works for you John, you may need to test other zip files to ensure your zip program is working right. If that the case I could upload all the images to an FTP for you as I got the Lite web paln with you guys
