Thumbnails not appearing

[eshlie]

Well not long ago my host changed servers and since then my gallery thumbnails are not showing, they either show the trashcan or they just don't have an image and just empty.

I went into admin tools and updated thumbnails and that worked...but only for some of the thumbnails, there are still over 100's missing, i tried updating the thumbnails doing all the files at a time and then trying less files at a time, also unticking the box and doing single albums and all albums to try everything out, but the same files are still not appearing.

I uploaded new files to test and it is making new thumbnails fine, my permissions are also all set to 777 where they need to be.

A link to my gallery is http://tevita.net/sitemodelgallery

Any help would be much appreciated!

Just tested some pictures with missing thumbnails:

1.) http://tevita.net/sitemodelgallery/displayimage.php?pid=1367
- full-sized picture exists: http://tevita.net/sitemodelgallery/albums/userpics/10001/131~0.jpg
- intermediate-sized picture doesn't exist: http://tevita.net/sitemodelgallery/albums/userpics/10001/normal_131~0.jpg
- thumbnail doesn't exist: http://tevita.net/sitemodelgallery/albums/userpics/10001/thumb_131~0.jpg

2.) http://tevita.net/sitemodelgallery/displayimage.php?pid=5175
- seems that no picture file exists

3.) http://tevita.net/sitemodelgallery/displayimage.php?pid=2837

Do you get any error messages at the admin tools? I think so, please post some of them.

The error messages I get are:

ERROR creating: albums/userpics/10001/thumb_93By89y~1.png
ERROR creating: albums/userpics/10001/thumb_81~2.png
ERROR creating: albums/userpics/10001/thumb_85~0.jpg

ERROR creating: albums/userpics/10001/thumb_95~1.png
ERROR creating: albums/userpics/10001/thumb_98~3.png

and so on for each one that doesn't work, but that's the only message..

The reason is quite easy: the full-sized pictures also don't exist for those images, at least your server tells that when I try to view them in my browser. Check yourself:

Without those images Coppermine of course cannot create thumbnail images.

So are you saying that I am going to have to go through and delete all the blank pictures that aren't showing up and re-upload them?

Uploading the missing original files to their correct location on your FTP server should be enough. Don't forget to run the admin tools to create the needed additional files.
