Hello,

I am trying to get metadata to display and have been able to get the field to show, but rather than displaying text it shows a group of question marks instead of the text

like this - ??????????

My config file contains this - $conf['show_exif'] = true;
$conf['show_exif_fields'] = array(
'Title',
'Make',
'Model',
'COMPUTED;ApertureFNumber'
);
$conf['use_exif'] = true;
$conf['use_iptc'] = true;
$conf['show_iptc'] = true;

Hello
which one is problematic? Is it in both back and front end?

Your metadata may be in an odd text encoding or some other quirk. My crystal ball is broken. Have a link to an example image?

goldeneye243 · 2021-04-17 10:01:44

The information is entered using windows via file properties

I meant a link to a real photo image, not some screenshot, so one can see what is actually contained in the metadata. You mentioning Windows leaves the suspicion that it could be UCS-2 or UTF-16 encoding. Anyway, nothing to tell here.

+1
If that plugin can't read it that means your server can't and it's more likely due to the use of the generic windows explorer instead of a proper picture software

Interesting,

This is what I get with the plugin

This is what shows using irfanview on the original image

Looks like XPTitle is the name of the field, but I cannot get that to show...

flop25 · 2021-04-18 19:47:29

XPTitle and others XPsomething fields are proprietary fields used by Windows since XP as stated in their name

erAck · 2021-04-18 19:52:35

Citing from this Exiftool thread post:
"The "XP" tags are written by Microsoft products. These products have no qualms about messing around with your precious images (and a long history of corrupting metadata), so I would avoid them like the plague."

I have spent a bit of time looking at this and started to use a tool called Metadata++ to export the metadata and use excel to copy it to another field that can display - Almost there, but a bit clunky to do...

My current issue is that it is displaying ASCII at the start of the comment - Any way to remove that?

erAck · 2021-04-27 19:57:27

I'd rather try Exiftool to read those data and write it to other fields instead of messing around with a piece of software that is absolutely not designed for the task.

goldeneye243 · 2021-04-28 13:06:29

Understood - Although the tool uses exiftool, but with a GUI.

Any thoughts on the ASCII displaying?

erAck · 2021-04-28 18:18:23

I was referring to "use excel to copy it to another field", Excel is a spreadsheet software.. I've no idea what you mean with "is displaying ASCII at the start of the comment".

goldeneye243 · 2021-04-29 08:04:18

OK - The use of excel is because I am familiar with it - It seemed to work quite well.

This is the ASCII error
