[Typo3] problems after clearing typo3temp/pics

[Alex van der Baan]

Hi everyone,

Yesterday I ported my website from my local linux box to our providers 
machine, since they gave me a hard time importing the database, I 
decided to import and export t3d files.

Since I started with importing and later ftp'ing the files some images 
were transfered but of a really bad quality (pdf datasheets). After some 
searching I found the location that Typo uses to store these preview 
images of a pdf file, typo3temp/pics. Initially I couldn't flush this 
folder due to the fact that typo3 created the images thus giving the 
files the nobody user instead of the user given to me by the hosting 
provider. After a chown on the side of the provider, I flushed the 
folder. I would have expected Typo3 to regenerate the preview picture 
from the PDF. Unfortunately this doesnt happen, do people here have 
experience with this? Or know how I can replace bad quality graphics to 
newly generated ones?

Thanks,

Alex
