the image not showing because contains errors"

[blackhumor]

After a server reboot many of my images (thumbnails) are not showing in the site.

The message I receive is "the image xxxxxxxxx not showing because contains errors"
This applies in products and categories thumbnails...

Examples
categories http://zografiki.com/ekklisiastika-eidi/ekklisiastika-eidi-oikias/stauroi to http://zografiki.com/images/stories/virtuemart/category/resized/53d288123be13_250x250.jpg
products http://zografiki.com/spiti-kipos/anthi-technita/mpales to http://zografiki.com/images/stories/virtuemart/product/resized/mpala-anthos-ms-mpala-anthos_250x250.jpg

Any idea what is the problem?

Directory ownership not correct ?

Large images are displayed normal but:

The path to images is .../stories/virtuemart/...

Which version of VM are you using?
Did you update PHP?

Those images contain no data to display (0 bytes). So there is no file header which the browser or an image editor can read. You will have to delete and recreate those thumbnails or use ftp to upload and overwrite the damaged thumbnail files with good ones.

Just to help someone that has the same problem...

I delete the thumbnails directory of all the products and the categories thumbnails and then I let the site to re-create the thumbs from the begining

Nice, and there is actually a button for that among the tools section. :-) The problem here imho was the update of the server and some malefunction with the thumbnail function. A deleted thumbnail is automatically restored.
