I’m working with images in WordPress responsive themes for access on mobile phones. I find that if an image has no caption it works fine, but if it has a caption, it does not shrink to fit on my mobile (cell) phone (Nokia C5-00). I guess the problem is the width and height values WP puts into the caption code. If i strip this out or change it to percent values, it either breaks or shrinks the image. Please see my test demo at timbaggaley.co.uk/test.
Note the image with the caption will scale in a browser window on a computer, but does not fit on my mobile. Does anyone know how to fix this?
