Images not showing on front end

[Crusty]

found the code that produces the thumnails, from what i can gather it goes looking for the created date. The problem i have is that i'm +15hours time difference from my server. is there a way the code can be changed or flagged so that it will auto update from new pictures? or a manual create thumnail from the backend by a button to auto update thumnails?

tell me if i'm waay off target here.

this is the code i found in ps_product_files.php
it starts at line 128

This is the same problem that i am having. All worked fine until I changed the details in a category then the thumb of the product doesn't show even though it seems to be there. If you click on it the larger image opens.  All permissions OK. Several themes tested. Error reproduced a couple of times now (arrrrg)
Do you any of you clever coders know what this might be?

Well, I just found one way out  -I hope - Upgrade joomla to 1.5.2 and vm to 1.1.0
