Is there an option or tool in the Canon program to create/save slideshows?
Google "slideshow maker"
Microsoft has a free one. This will create a WMV file that can be uploaded to Flickr or Photobucket, as long as you don't exceed the file size/clip length limits or violate content restrictions:

Flickr takes the following video formats:
* AVI (Proprietary codecs may not work)
* WMV
* MOV (AVID or other proprietary codecs may not work)
* MPEG (1, 2, and 4)
* 3gp
* M2TS
* OGG
* OGV
Photobucket: 3g2, 3gp, 3gp2, 3gpp, 3p, asf, avi, divx, dv, dvx, flv, gif, moov, mov, mp4, mpeg4, mpg4, mpe, mpeg, mpg, m4v, mts, f4v, qt, wmv, xvid, rm. All video files are converted to mp4 format when you upload them
Photobucket Pro accounts have less restrictions and doesn't convert some formats to MP4.
Or upload the individual photos as a set or folder on Flickr or Photobucket, share the folder or set and they can be viewed as a slideshow. Photobucket has a slideshow tool but you have to use their styles which may not give you the effect you want.
Or convert the images to GIFs and build an animated GIF, provided you have a program to do this. Google search "create animated GIF"
