I have changed all my php.ini settings to allow me to move large files (i set it to 50M) but I have had 2 strange problems.

I cant upload a file larger that 2M , it looks like its uploading, but it just dosen't.

the second and much stranger is zenPhoto is not importing my exif tags from any file larger than 1,792kb I have a number that close because i have several pictures up, and the next file up is 1799kb and it dosnt show any tags, the downloaded full size version does.

anyone else run into this?

You should probably check your CGI error logs to see if an error has occurred. Perhaps there is not enough server memory allocated to PHP to support that size of image.

first, your promptness never ceases to amaze me. Thank you so much for all your hard work!

what would be the best way to force zenPhoto to refresh its database from the tags in the images, and second, where would the error_log get generated?

I think your right, that it is something with my host. But unless I know what to tell them to fix, their tech support reps don't know what to tell their actual technicians. Thank you again for all your time and energy!

what would be the best way to force zenPhoto to refresh its database from the tags in the images

There is a utility on the admin overview page and also a button on each admin album edit page.

and second, where would the error_log get generated?

You need to ask your host where that is.

Please see the troubleshooting to learn that is its the actual px dimensions of the image not the file size that matters.

I have set and tested through other scripts (ok had tested for me by a technicaly superior friend) that

file_uploads
upload_max_filesize
max_input_time
memory_limit
max_execution_time
post_max_size

are all set to 200Mb. well except the time ones that are set to over 2 min each. There has been no improvement in reading the exif data when refreshing the metadata...

my php error_log and my cgi error log are not showing any errors during my refreshes. in fact the only errors it shows are a few from installation, and a few more from when i was trying to tweak the theme.

upon further testing the filesize must have something to do with the issue i am having, by opening the picture in photoshop, compressing the heck out of it without reducing resolution, then uploading it again, the files tags show up.

Found it!

the pictures that are not reading properly were tagged with Windows Live Photo Gallery, the ones that work have either been saved by photoshop sense then, or were tagged in the original Windows Photo Gallery.

however something I changed from the list in my last post has fixed ALL the upload issues. I have uploaded a 2Mb and a few 5Mb pictures using the flash uploader!

anyone interested in comparing the headers of 2 extremely similar files to see what M$ might be doing strange if not wrong?

If you have an image that reliably fails, You can create a ticket and attach it to the ticket. We will then look at it.

i will try and track down exactly what causes it, but I ran a script last night to have photoshop open all my photos, and save them at "level 10" compression. This shrank many of the photos, but plenty of them are still above 2mb, plenty of them are above 3000x2000px . The metadata refresh worked on all of them, as far as I can tell.

I will try and create the smallest image that will fail, and then save it through photoshop so there is a version that works.

I read that in the future imagemagic may be an option, is that still in the works?

I've been working on getting a working version of the Imagick library prepared for zenphoto. Hopefully something more substantial will be out soon that you can use.

hello,
I've make a try with my folder fill by 3648x2736 pictures.
I've changed the limit of 3000 pixel to accept my resolution in php fonctions file.

before starting the httpd process use 20 Mb of Memory.

when I update the cache by the button in the admin panel, in the middle of the process, the httpd increase to around 260 Mb at full bandwith.

but in the other side, the computer running firefox to doing this is quite .... on the knees !!!
1 600 Mb for memory to firefox on the middle of the process, when it's displaying and retrieving.

so if you have to update a cache very big and that your computer might be a little slow, try to update album or (sub album) by album
this test has been done on a local network so the bandwith is very good and the server is on Windows with xampp
