Custom Field Image Availability Restricted

[IntrepidClassChicken]

Hey folks,

I have a really frustrating error happening.

I have created a custom field to display examples of different coloured tiles. The main tile as the product and then it is represented with smaller thumbs underneath in different colours. I have uploaded both the full size image and thumbnails into the virtuemart image folders:

/public_html/images/stories/virtuemart/product

and

/public_html/images/stories/virtuemart/product/resized

Yet when I try to add these images to the custom fields I get a random selection of available images. The selection of which is just not representative of the contents of any real folder on the system.

What could be going on? How do I add the proper images from the correct folder?
