Many thanks! I can't see any option to change the alignment in slideshow other than to align text to "top" or "bottom", and I've not had any luck amending the source code directly to style="text-align:right", or left, to position the image/text in slideshow. The image doesn't show in the source code view at all. Will keep trying, am sure I'm just missing something.
Sorry I'm going offline now but a quick suggestion:
It sounds like you have added the image via the image optional property? Instead remove that optional property and add the image via the wysiwyg editor e.g. tick the box to show tools and use the add image icon/button. Put the cursor to the left of the first line of text, add the image, set the image width to a percentage e.g. 40% and set the alignment to right.
