[show thumbnails] works on IIS5 but not in IIS7

[antonio]

hi all,
I've just transferred a site to a new webserver featuring win2008 server.
All works, except dynamic images.
I have a "show thumbnails" behaviour on a page but I cannot undertand why I get a "image not found" square where there should be the image thumbnails.
I double checked the image path but it's ok.
I double checked the folder permisison too; they seem ok.
Have I to set specific folder permission on the upload/thumbnails folder in IIS7?
Or is there any specific settings I should check (well, not me directly, but who is housing the server...)?

Tony you can ask the host to check the error logs to see if there is anything showing up.
If like you say in the other post the English version is working then the folder permissions should be ok.

Yea it is a pity about the interakt site.
Adobe just keeps on ignoring my requests for a copy of the database.
