In a web application I am using images sprites that have alt text. But in Firefox only the actual alt-text overlays the image on screen.\[code\]<img width="36" height="36" class="step1Current" title="Step 1" alt="Quote step one image">\[/code\]Its class is:\[code\].step1Current{ background: url(../images/progress-sprites.png) no-repeat; background-position: 0px 0px ; width: 36px; height: 36px; }\[/code\]So the image is overlayed with the text 'Quote step one image'.
