Hi christopherm,
I think I might have gotten this working. When I clicked on the image–>edit, I found that there was a box in the settings that I hadn’t checked before … for “custom link”. It seems to be the missing link (no pun). I tried linking it to my existing Flash slideshow in my old website, but my phone says it doesn’t support Flash. But that told me that I had probably succeeded in the linking. So now I guess I should set up a separate slideshow in BoldGrid and then link to that? Will try that and see.
Thank you so much for your response!
