Thumbnails creation stopped working

Post by gabrix73 »

Hi everybody,
i run ubuntu trusty and i have phoca gallery on joomla 3.4.5. After some OpenJDK java7 upgrades phoca gallery thumbnails creation stopped working. The issue IMHO might come also from a procedure error which is quite simple. I first create a category than i go on images and multiple add ,create a directory, upload pics, than select the pics i want thumbnails from and save, but thumbnails don't get generated anymore. I have followed the guide and thumbnails troubleshooting on this site and permissions are correct, GD library is working, images file type are also correct !
I hope your help, any other infos just ask ... please :x
regards

Thanks for your answer ...
Thumbnails creation is switched off. I turned it on and everything is fine until it stays on ,but for some reason thumbnails generation stops (all images are jpg) and thumbnails creation status switches back off by its own !

Hi,

found thread, with similar problems acc. this feature: viewtopic.php?f=1&t=38035

also:
... the process will be stopped but the automatically thumbnail creation will be stopped too. It is because Phoca Gallery automatically creates thumbnails and if there is some problem this automatized task needs to be disabled. After the problem is removed it can be enabled again. So disabling the functin while clicking on the link is OK. This is a feature. Jan.
Could be also browser problem, limitations etc. .... loading of too many images at once .....

Kind regards, Christine

Hi,
try to check:
File size, file names (no spaces, no special charcters...), only .jpg & .png files, check if the image files can be displayed in browser... etc. if it's not possible to display the image file in browser, the file could be damaged :idea:
Try to load up the 3 files one after the other (not multiple add) and find out which one works and which not. Then compare the file which works and which not works. Search differences. :idea:

Kind regards,
Benno

Normally you only need to delete (e.g. via FTP) the /images/phocagallery/thumbs/ folder(s) :idea:

Hi,

try to delete it and then per ftp try to refresh the tree (to be sure, the files were really removed).

This error message just comes when the thumbnail exists and the script will not write new. But be aware, if you e.g. moved some images, etc. it can happen, that the thumbnails exists on other place - not in the same directory ... so the image file name should be searched if it does not exists in the folder images/phocagallery in ohter place)

Phoca Gallery creates only one instance of thumbnail, so e.g. if images are moved, used more times, etc, so the place is saved and not more instances created.
