Thanks - this was a HUUUUGGE help.
One issue though that I found. When adding the image to the child item row, the bottom of the image starts flush with the child name, which is centered vertically on the row. Note that the price, quantity, and quantity arrows are bottom aligned vertically. When not using child images, it's not much of an aesthetic issue, but when adding images the image size is generally larger and inevitably will increase the row height. If the image were bottom aligned (similar to the price, quantity, and quantity arrows, it will help reduce the row height per child. This is especially useful when having a number of child rows, to reduce unnecessary scrolling for the customer.
Does anyone know how to get the image we've just created per the above hack to bottom align in each row? I've attached an example of the issue with my cart.
Thanks in advance.
