Browsers cannot scroll content that is too short to fill the space it is scrolling in. They will simply run out of things to show.
If you want something like that with a gap to fill out the empty space, just place a span or blank image of the desired width into the contents. For example:
Code:
<div class="marquee" id="mycrawler2">
<img src="blank.gif" width="300">
<img src="http://i40.tinypic.com/9tlic8.jpg"> <img src="http://i43.tinypic.com/1zbqs5t.jpg"> <img src="http://i44.tinypic.com/2419ul3.jpg"> <img src="http://i43.tinypic.com/296nh3r.jpg"> <img src="http://i40.tinypic.com/mk7ki.jpg">
</div>
Where blank.gif is a transparent .gif image, adjust the width attribute as needed. There are various ways.
On the other hand you, if want continuous scrolling even though there isn't enough content to fill out your desired width, repeat all or some of the images you do have.
