Thumbnail images (category, detailed) not showing

I've been trying since last night to get some images up for new listings on my site (www.missionarydecals.com) but for some reason the category images and detailed images won't display. Supposedly they're loading just fine.

An example of a functioning listing: Products_Detail.php?ProductID=3789

An example of a non-functioning listing: Products_Detail.php?ProductID=3791

I only have a basic familiarity with website coding, and my brother helped me build this site. If there are multiple steps to solving this problem (I've heard it has something to do with checking the number of "permissions") please give details. Thanks you guys.

using an FTP program like FileZilla, connect to your webaserver.

In FileZilla, right click the imagesupload/ folder and select File Permissions.

In the numeric value section, type 755

check the "Recurse into Subdirectories" option and select "Apply to all files and directories"

Thanks Jason. I connected to it using a Globalscape program called Cute FTP 8 Home edition.

We were able to do the "755 permissions" part but not the "recurse all directories" part. Please advise.

looking at the help documentation for uteFTP Home edition, it does not look they have the option to recurse through subdirectories, you will need to manually do this to all files and folders under the imagesupload folder, or use FileZilla instead which does offer this option.

I was able to fix the issue last night, but it's doing it again today with some new images, and according to my FTP, the permissions are set at 755. Is there something else I can do this time?

I have created a support ticket so we can look into this issue further.
