Images using the default uniform framework will be sized to allow large words to wrap well in most browsers/platforms.
Rule of thumb: don't set height or width for images. There's no point setting a width, because it will be reset by the stylesheet. If you set a height, you will be overruling the browser's proportional sizing (based on the width set in the stylesheet) and your image will appear disproportionate or "stretched."

There are three sizes for images: full-unit (default), "small" and "detail." "Small" dimensions are determined based on the size of the parent unit. For instance, a small image in a span-5 unit is 132 pixels wide, whereas a small image in a span-8 unit is 236 pixels wide. Detail images are 62px wide — the width of one column. Small or detail images can float left (text wrapping around the right) or float right (text wrapping around the left).
Common default image sizes in plain units:
span-2 136px | span-3 210px | span-4 284px | span-5 358px | span-6 432px | span-7 506px | span-8 580px
Common "small" image sizes in plain units:
span-2 38px | span-3 76px | span-4 118px | span-5 148px | span-6 177px | span-7 207px | span-8 236px

Here's how a small, float-right image in a tinted span-5 unit should look in your code (below) and on your page (at right):
<div class="unit span-5">
<div class="tinted">
<img src="gymnast.jpg" class="small right" alt="gymnast">Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam.
<div class="clear"></div>
</div>
</div>
