I ran into a similar problem. I uploaded 10 images to an album, but only 9 showed up. No matter how many times I re-uploaded the missing image, it would not show up and I did not get a confirmation after the upload. So I thought perhaps there was some sort of problem with the image itself. I opened the image in my photo editor, re-saved the image, and uploaded it again. Voila, it showed up!

I recreated jpg file and it still not worked (upload from Administration Home -> Add).
I tried to upload to different albums with the same results. After upload is completed I get a quick message "successful” but I never get the thumbnail on the screen and photo is not there.
I could upload other pictures without any issue so it looks like something related to picture(s).

I also tried to use pLoader and it seemed to work. I used the word “seem” since there is a small issue with that photo. It shows correctly on the screen and all functions work but one, “click on the photo to see it in high definition”. A am using “Look_like_gbo2” plug-in. I tried to turn on/off that feature but my “bad” picture is stubborn. All other functions seems to be working on mouse move over the picture (next, previous, thumbnails).

Thanks

I went deeper and checked the MySql and directory structure. I believe that there is the issue with updating album (removing/reading images)

1. Here is the listing of my directories:

jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07]# ls -l
drwxrwxrwx 6 jolajerz jolajerz  4096 Jul 13 15:52 ./
drwxrwxrwx 3 jolajerz jolajerz  4096 Jul 10 17:47 ../
drwxrwxrwx 4 jolajerz jolajerz 12288 Jul 13 16:13 10/
drwxrwxrwx 4 jolajerz jolajerz  4096 Jul 11 20:41 11/
drwxrwxrwx 4 jolajerz jolajerz  4096 Jul 12 19:44 12/
drwxrwxrwx 4 jolajerz jolajerz  4096 Jul 13 16:22 13/

So it looks like I uploaded photos for 4 days, starting July 10 and last upload was done on July 13.

2. I run a simple loop to count all my photos:

jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07]# for day in 10 11 12 13
> do
>  no=$(ls -l ./$day/*.jpg | wc -l)
>  hno=$(ls -l ./$day/pwg_high/*.jpg | wc -l)
> echo "Day= $day  Number_of_images= $no  Number_of_high_images= $hno"
> done

Day= 10  Number_of_images= 108  Number_of_high_images= 163
Day= 11  Number_of_images= 14  Number_of_high_images= 34
Day= 12  Number_of_images= 1  Number_of_high_images= 2
Day= 13  Number_of_images= 2  Number_of_high_images= 11

If I add all numbers in 2nd column (Number_of_images) it gives me 125 and it is equal to number of pictures in my album. So far so good.
But why the number of high resolution images (3rd column) does not match number of photos (2nd column)?

3. Let's check MySql now:

The “piwigo_images” table has 125 records. It is equal to number of photos in my album. It looks like database has been updated correctly.

4.Let's remove one photo, the one I uploaded on July 12 ( Day= 12  Number_of_images= 1 Number_of_high_images= 2) and see what happens.

Before (just changing to July 12 directory)

jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07]# cd 12
jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07/12]# ls -l *.jpg
-rw-r--r-- 1 jolajerz jolajerz 173335 Jul 12 19:44 20110712193020-14b2b224.jpg

jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07/12]# ls -l ./pwg_high/*.jpg
-rw-rw-rw- 1 jolajerz jolajerz 457249 Jul 12 19:26 20110712192628-21f434a4.jpg
-rw-r--r-- 1 jolajerz jolajerz 457249 Jul 12 19:41 20110712194142-21f434a4.jpg

By just looking what it there none of the two files inside pwg_high directory is high resolution jpg for the photo in parent directory (20110712193020-14b2b224.jpg). That is probably why “Click on the photo to see it in high definition” dos not work.
Actually, to be more precise, the HTML code was never generated to do so (see below)

<div id="theImage">
<!-- LLGBO2 picture_content -->

    <!--  navigation on picture  -->
    <map id="prevnext" name="prevnext"> 
    <area shape="rect" coords="0,0,192,600" href="picture.php?/20/category/2" title="Previous : "  alt="" rel="prev">
    <area shape="rect" coords="192,0,608,300" href="index.php?/category/2" title="Thumbnails" alt="" rel="up" >
    <area shape="rect" coords="608,0,800,600" href="picture.php?/7/category/2" title="Next : "  alt="" rel="next">
    </map>
     <span  id="gboh2" style ="background:transparent;z-index:3;color:#111111">BMW Museum</span>
    <div  id="gbo" style="width:844px; height:644px;">
    <div id ="llgboframe31" style="border: 1px solid #666e83">

Here is also database record for that one photo from July 12 before removal:

Deleting photo now (Albums → Manage → checked photo → Action → Delete Selected Photo)
GONE

Checking directories:

File disappeared from ~/www/jjalbum/upload/2011/07/12 directory and there are still 2 jpg files in pwg_high directory as we expected since there have nothing to do with original photo.

Checking MySql:

Record is gone.

5. Re-adding the same photo (Photos → Add → To existing album):

No confirmation thumbnail on the screen.
Let check directories:
Obviously there is a new directory for July 14 but it is empty but pwg_high has one file.

jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07/14]# ls -l *.jpg
/bin/ls: *.jpg: No such file or directory

jolajerz@jola-jerzy.us [~/www/jjalbum/upload/2011/07/14]# ls -l ./pwg_high/*.jpg
-rw-rw-rw- 1 jolajerz jolajerz 457249 Jul 14 12:28 ./pwg_high/20110714122851-21f434a4.jpg

and there is no thumbnails directory either.

Let check now how MySql has been updated:

The same number of record as before – 124. It means that nothing has been added.


CONCLUSSION:

There must be a bug in the php code in adding photo module. I will be more than happy to do more debugging. I still cannot understand why I can upload some photos without issue to the same album.

Also with pLoader I have no issues (I enabled HD and both images are there).

Thank you.

Resolved.

The issue was related to PHP configuration.
I found many comments regarding that issue that suggested to change the following variables (increase size) in php.ini file;

upload_max_filesize = 10M    ; default value
post_max_size = 8M        ; default variable

some suggested increasing to 200M!

The real issue was the amount of memory (limit) that is allowed to be used by script.
To correct that you can try to increase memory from default value (in my case 64M) to something bigger. I just doubled it to 128M.

So the entry in php.ini should look like:

memory_limit = 128M    ; Maximum amount of memory a script can consume.

I tried that without making changes to “upload-max-filesize' and “post_max_size' and upload from inside PiWigo finally worked.

Jerzy.

Just as an addendum to this solution, for those on shared hosting environments you can tackle this restriction by adding the php.ini to the root of your piwigo installation as well as the root of the uploadify plugin in /admin/include/uploadify/

I have detailed what I have done on my own blog, http://www.mainframes.co.uk/index.php/2 … out-error/

Barry.

Great post Barry, we'll add your solution in the wiki.

Did you try with Piwigo 2.3? The upload form has been modified a lot and you should get useful information before you select and upload photos.
