I'm with BT Internet which uses Yahoo's Neo Mail and have the same problem (plus others). This applies to every browser I have tried (Firefox, Safari, Chrome, SeaMonkey, Camino, Opera).

I sometimes find opening, closing, re-opening an email prods the slideshow into action.

Problems include: email thumbs don't show pics (slideshow thumbs usually do), pictures will not load in slideshow, if they do only first eight or so load (sometimes cured by scrolling through thumbs in email).

Also slideshow crops many pictures, but is OK full screen.

This is on Macs running 10.6.8 and 10.4.11 with latest versions of Firefox/TenFourFox.

Googling shows other people have this problem.

Sounds as if there is no out and out fix but thanks for the info; will try your tips as needed.

Many thanks. Glen

The new Camino 2.1 (which isn't officially supported by Yahoo Neo Mail) works OK with slideshows for me BUT…

Only pics whose thumbs have appeared in the email window will load in slideshow. However if I scroll to the end of the thumbs in the email all will load fine in slideshow (though some are still cropped unless I go to full screen).

This post I made elsewhere suggests a possible workaround.
