Hey Paul,
I generally don't have much problem with Photobucket and this board software, though I'll admit I now tend to post more w/ImageEvent than Photobucket.
I played with your example a little and got something to work, at least for Chrome and Firefox browsers (Flash appears to be required). See below the code block for details:
T207 - In reverse order (Photobucket)
It only works - as far as I can tell - by side-effect, in that the "Code" box has to be full of stuff that doesn't show up but makes the box tall enough to be useful (i.e. without the scrollbar). The way I did this was to put other non-printing HTML components at the top, like a style declaration, for example - either above or below your embedded Photobucket slideshow div, text like:
<style type="text/css">
div.unknown
{
width: 220px;
padding:10px;
margin:0px;
}
div.unknown2 {
width: 220px;
padding:10px;
margin:0px;
}
div.unknown3 {
width: 220px;
padding:10px;
margin:0px;
}
div.unknown4 {
width: 220px;
padding:10px;
margin:0px;
}
</style>
If you know what you're doing, you can (I believe) modify things to some extent, like getting looping to work so you show just runs... its just clunky.
ImageEvent's slideshow is javascript-based and does not look to have an embeddable form - with only a cursory glance.
