Topic: Amend the PHP script NOT to overide the captions
Great application and thanks for being so generous as to share it with us!
I think it would be most beneficial if the PHP script is amended so as everytime it runs to update the XML file with the image content that it does not override existing images that have captions attached to them. This would avoid the redundancy of downloading the xml file again and reinserting the captions of the old files.
So the PHP script would intelligently check existing images in the Images folder and if they are already referenced in the XML file they are left. I guess however this depends if the PHP file is set to write to the XML file rather than create a fresh one each time. Just a thought.
