Playtime on p. 134 has got an item that asks us to try adding an item in the cart by clicking on the item image. Well, it works when I use the form_remote_tag and image_submit_tag instead of image_tag.
But what happens is my images become bigger (maybe because image_submit_tag creates an input form field whereas image_tag creates an HTML img tag). I am not sure how I can control the size of the image (because there is no provision of something like :size on image_submit_tag).
Can someone help?
