Slidesow with meta data titles

Post by tallstory » Tue May 15, 2018 1:56 pm

I have been trying this new feature where the slides are stored in my web server directory. This works fine but I can't get it to display the titles from the metadata embedded in the files. I used exiftool to copy the filename into the meta data but I am unsure what command to use. I tried exiftool "-title<${filename;s/\..*?$//}" DIR and exiftool "-iptc:caption-abstract<filename" DIR but neither displayed the title in the slideshow.

Can anyone help please?

I'm sorry, I cannot help you with the use of third party tools.
I have used 'Properties->Details' in Windows Explorer to update the meta data.

Yes I understand but can you tell me what you changed under Properties>Details. If it is title this is what I have changed using the batch file processor (I have over 200 files to do).

I changed title and subject fields.

Technical details:
Web Builder reads the data: PropertyTagImageTitle and PropertyTagImageDescription

As explained here:

Thanks for fast response. Yes it works if I do that manual change of title and subject. Do both have to be changed for it to work?

No, I think it also works with the subject only.

I have done some tests and it appears that both meta tags have to be changed. Couldn't WWB look for one or the other, rather than insisting on both? It would be a great help since changing the title tag is the easiest for batch files to handle.

For the online script you only need 'ImageDescription'

Thanks to Pablo's help I have managed to insert the filenames of the slides into the metadata using a batch file so that it it is displayed by WWB Slideshow. In case anyone else has too many slides to do this manually, here is how to do it:

First download exiftools from the web. It's a free utility and its only drawback is that it is a command line app and has to be run from Windows Command Prompt.

put exiftools into a directory, open Command Prompt and and navigate to it using good old DOS commands.

Enter the command exiftool "-Exif:ImageDescription<${FileName;s/\.[^.]*$//}" dir

where dir=directory containing slides. This sets the image Description from the file name after removing the extension.

Then copy the slide files to your remote server.

Hope this is useful for someone. :D
