    #foo > IMG:first-child {/* first of two IMGs */}
    #foo > IMG + IMG       {/* second one */}
    

    Works in all browsers including IE7+.

    It depends entirely upon which image you want to target. Assuming it's the first (though the implementations are similar for both) image:

    #foo img[src="bar.png"] {
        /* css */
    }
    
    
    #foo img[src^="bar.png"] {
        /* css */
    }
    
    #foo img:first-child {
        /* css */
    }
    
    #foo img:nth-of-type(1) {
        /* css */
    }

    • CSS3 selectors.

    You can add a class to the images OR

    .foo img:nth-child(2) { css here }
    

    or

    .foo img:first-child { css here }
    .foo img:last-child { css here }

    I don't know why everyone is so fixed on the #foo div. You can target the img tag and not even worry about the div tag. These attribute selectors select by the "begins with".

    img[src^=bar] { css }
    img[src^=cat] { css }
    

    These select by "contains".

    img[src*="bar"] { css }
    img[src*="cat"] { css }
    

    Or you can select by the exact src.

    img[src="bar.png"] { css }
    img[src="cat.png"] { css }
    

    If you want to target them both, then you could use the div id.

    #foo img { css }
    

    For just one of the images, there is no need to worry about the #foo div at all.

    div > img:first-child {/*the first image*/}
    div > img:last-child {/*the last image*/}
    

    That should do it.

    All of the following solutions only work in recent browsers.

    You can select by child position:

     #foo img:first-child { /* for the bar */ }
     #foo img:nth-child(2) { /* for the cat */ }
    

    You can select by child position, counting only images:

     #foo img:first-of-type { /* for the bar */ }
     #foo img:nth-of-type(2) { /* for the cat */ }
    

    You can select by image URL:

     #foo img[src^=bar] { /* for the bar */ }
     #foo img[src^=cat] { /* for the cat */ }
