This is a very easy to create slideshow. Upload all of these files (except Readme.html) and then upload the images into the same folder. Name them 1.jpg, 2.jpg etc (lower case).
The program here has room for 64 images, simply remove any that you do not need, or copy the last one and rename the image for additional images.

It can go inline with code like this:
<iframe src="http://javascriptwebdesigns.com/slide-show/index.php" width="100%" height="900"></iframe>

If you re-size all of the images to an 800 pixel width before uploading them, the height will be OK for most of them, even the sideways ones. Adjust that as needed.
