I'm runnning AspDotNetStoreFront Multistore 126.96.36.199 on your servers.
I have uploaded several products into the system using the Large Multi-Image Manager. I accidentally in the beginning uploaded my variant colors horizontally instead of vertically. To remedy the situation I have gone in and deleted the images (Horizontally max of 10) in all three Multi-Image Manger links (Large, Medium, and Icon). I have also gone and deleted any Color Swatch that might have been generated. I have then re-uploaded the colors correctly using the Large Multi-Image Manager matching the color swatch to the variant vertically.
Once done everything appears okay except the image won't change when a color is selected from the drop down. I notice that if I upload a product correctly from the beginning the follow code shows up on the color drop down on the site:
<select size="1" id="Color_97_196" name="Color_97_196" onchange="setcolorpic_97(this.value);">
For the products that were not uploaded correctly from the beginning I get this code for the drop down on the site:
<select size="1" id="Color_167_266" name="Color_167_266" onchange="">
The difference is the onchange, which I have highlighted. Is there a way to fix this or do I have to delete the item and redo? I praying for an easy fix.
