How do I display EXIF?

[codfather]

Hi,

Currently have 4.6.7 installed on Pair Networks and have "/usr/bin/jhead" as the path to J Head in config and set admin to display EXIF information but nothing seems to come up.

What am I doing wrong and how do I enable it?

Thanks,
Kerry

1st, double check the path with your host. Sounds like you're not sure it's there or not.

And it won't just magically appear. You need to upload an image with EXIF data.

Or, you can scan the db to extract the info from existing images.
(Admin,Scan database, Click here to rescan photos and save EXIF information)

Apparently jhead is not installed, how do I install it myself?

[codfather]

s'ok found out how to do it.

Here is how I did it, just download the pre-built executable for your system:

http://www.sentex.net/~mwandel/jhead/

and upload it via FTP in binary mode to a folder on your site, CHMOD it to 755 and remove any .txt extension and update your config path to jhead appropriately.

Remember to run rescan photos and check for EXIF in scan database on admin.

I did all that, but no Exif information although there must be some in the gallery

What else can I do?

EXIF data is only gathered when the image is uploaded, or you do a scan in the Admin panel.

[snoopy5]

Version PP 4.7j

I did do the scan in admin panel, but the message comes:

And there have to be exif data!

Because of this alert, I guess the jhead must be installed properly and the path also correct, right?

Or does it even show this info without the properly installed jhead?

What makes you sure there IS exif data in those images?

In admin, do you have "Display and extract EXIF information from images?" set to yes?

Have you confirmed you have the right path to jhead by trying to run it in a shell? You won't get an error when you scanned. My system doesn't have jhead installed and my scans look just like yours...

When you installed jhead where did you install it to.

If you dont run your own server and do not have access to root it definately will not be in /usr/bin as you would not have access to that.

The only people who have access to the root system are dedicated server people and people who run a VDS system on a shared system( Virtual Dedicated Server).

I do not give too much credit to precompiled binaries. The time accepted method to ensure software is truly compiled on a server is to drop source files and configure and build it with the GCC compiler.

o.k., I tried it again...

PP 4.8c

I downloaded the jhead file for non-root access ("Pre-built Linux executable built on RedHat 7.2") at:

http://www.sentex.net/~mwandel/jhead/

I created a "bin" folder on my server and uploaded (ftp) in binary mode this jhead file into it. Permissions 755. I deleted the .txt ending and the file is called now only "jhead"

I set then the path in config (admin menu) to this directory to the file (incl. the file name in it).

I uploaded a photo which has exif information (100% sure)

I rescanned all photos in admin menu with the option:

"Check here to rescan photos and save EXIF information."

The result is the same as above, no exif information.

I checked my server with phpinfo, this is the information:

----------------------
EXIF Support enabled
EXIF Version 1.4 $Id: exif.c,v 1.118.2.27 2003/12/17 09:08:37 helly Exp $
Supported EXIF Version 0220
Supported filetypes JPEG,TIFF
-------------------------------

I use GD2 for thumbnailing, if this is of any interest in this case

Where is my problem? What did I forget?

[Chuck S]

I never use or trust precompiled binaries. you can send me the image you are 100% sure has exif and I can test it

[snoopy5]

If I reduce the image size for sending via e-mail, do I loose the exif data?

If yes (it is a big image), any place where I can upload it for you?

For which question was that meant to be?

[Chuck S]

seffern usual email accounts can take up to 10mb I doubt your image is that large. I dont care if is a meg or two

[snoopy5]

...I sent it to you...

[Chuck S]

Gotta be your install of jhead

http://www.reeftalk.com/gallery/showphoto.php?photo=738

Instead of using a precompiled try compiling your own or as suggested. It may be as simple as you using the wrong type of compiled binary.

[snoopy5]

"Instead of using a precompiled try compiling your own "

What is compiling? and how do I do this?

[Chuck S]

Using SSH login and using the source all you should have to do is the following

gunzip *.gz

tar -vfx jhead-2.1.tar

cd jhead-2.1

make

THATS IT

[snoopy5]

I did that now with version PP 4.8d and jhead 2.2.

When I type the command "make" and hit return I get the folowing in SSH:

--------------
cc -O3 -Wall -c jhead.c -o jhead.o
cc -O3 -Wall -c jpgfile.c -o jpgfile.o
cc -O3 -Wall -c exif.c -o exif.o
cc -O3 -Wall -c makernote.c -o makernote.o
cc -o jhead ./jhead.o ./jpgfile.o ./exif.o ./makernote.o -lm
-------------------

The result is a directory on my server called jhead-2.2 with different jhead files in it.:

exif.c
exif.o
jhead
jhead.1.gz
jhead.c
jhead.h
jhead.o
jpegfile.c
jpegfile.o
make.bat
makefile
makefile-win32
makernote.c
makernote.o
myglob.c

I set all to 777

in admin menu edit config I set the path to that directory. I also tried it with the path to the jhead file without any extension within the directory. I rescanned with exif option - no success

Doe this jhead directory has to be installed within the directory of the photopost installation?

I use linux server, dedicated server but no root access. But I have shell access and the commands you gave me worked (although I use tar -xzvf instead of gunzip)
