possible jrStore issues

We have this in jrElastic's list template in the jrStore module: {if strlen($item._product_images.0)}. Does this imply >0?

Also, let's say the product is a t-shirt and I'm uploading a front and back image. I upload the front first and the back 2nd. On the form page, the front appears first, the back 2nd. On the product page the front is displayed with a (2) showing more than one image is available. I can click on it and the front shows first and the back 2nd.

However, on a list page, the back side is displayed. Is $item._product_images.0 the last image uploaded? I believe you would most likely want the same image displaying in a list as the primary image which is displayed on the product page.

Nope, that reads, "If the string length of the first item in the _product_images array is greater than zero"

So its checking that there is a product image set.

I would expect that the order of the images would always have them in the same order, so _product_image.0 should be the same in any location. If its not, then it could be that the product images are being sorted.

URL's to see locations where it happens please.

On the index page here http://blindmime.com I have list of merch on the right. The Henry the Lima Bean t-shirt in the list is showing the 2nd image I uploaded. Go to the product page and it shows the 1st image I uploaded.
