if you are using the Dreamweaver fluid grid feature your default set up should look like this:
img, object, embed, video {
max-width: 100%;
}
/* IE 6 does not support max-width so default to width 100% */
.ie6 img {
width:100%;
}
Try this:
object, embed, video {
max-width: 100%;
}
#map_canvas img { max-width: none; }
/* IE 6 does not support max-width so default to width 100% */
.ie6 img {
width:100%;
}
just replace the code as it is.
