How to float paragraph next to image without wrapping the image?

I want to float a paragraph next to image, but without wrapping the image. Like this:

div.img {
        float: left;
        display: block;
        margin: 15px 2% 0 2%;
        width: 26%; /* I cannot use that */
}

div.info {
        float: right;
        display: block;
        margin: 15px 2% 0 2%;
        width: 66%; /* The width should be variable */
}

The problem is that I can do it if I set width to both img and info but the image is a variable width/height. It does not have specific width/height.

I am almost lost in this situation. Please suggest to me anything.I want both divs to float next to each other without wrapping .. without specifying box width.

Any solution..workaround?
