cpg1.5.42 maintenance release - upgrade recommended
The Coppermine development team is releasing an update for Coppermine in order to fix several minor issues. All fixes are not security critical, so if your gallery is running fine with cpg1.5.36, cpg1.5.38 or cpg1.5.40 you don't need to upgrade. If you are running an older version than cpg1.5.36, you must update to this latest version as soon as possible because of the security impact!

Suggestion on the exposure time
« on: March 26, 2012, 02:59:20 PM »

I noticed that exposures longer than 1s are shown in tenths rather than in seconds, as shown here (20/10s instead of 2s) http://www.flapane.com/gallery/displayimage.php?album=search&cat=0&pid=896#top_display_media
Also, another pic in that gallery shows "10/10s", while a simple "1s" imho would be better.

I just tested with the latest version of the EXIF library (you can download it here) and it seems to fix that issue. Unfortunately the formatted data is stored directly in the database, so you'll either have to delete the EXIF data from the database (Coppermine will read it automatically on the next view) or reload it manually for each file.

Please replace Coppermine's include/exif.php file and report any unexpected behavior.

Thanks, I tried by manually deleting exif data just for the photo I linked above, and it works. I'll report any strange behaviour.
I can't manage to batch delete EXIF data for all the images in Admin Tools, should I manually delete some sql table?

Don't delete any table, but just clear the exif table (= remove all data). Something like
Quote
DELETE FROM cpg15x_exif
will do the trick.

Thanks, it worked.
There's only one thing left: whenever the exposure time is 1sec, it will show 1/1sec.

Open include/exif.php, find
Code: [Select]
if ($data > 1) {and replace with
Code: [Select]
if ($data >= 1) {
Please confirm if it works as expected.
