Hi,
unfortunately a new problem at my environment. Contact sheet with 5 images, select all, export with PM classic. OS X 10.6.3
index.html is opened in browser by default, I can see 4 images (1st missing). Then I click on 1st visible image to see the larger version. Yeeaaah, now I can click "Previous" and I see the 1st (missing) image. Now I can step through all my 5 images.
Back to start. Let's try again. index.html is opened by default, Browser shows "index.html". I click on the 1st visible image (it's image #2 because 1st is still missing) and Browser shows "page2.html". I click on "Previous" and see my missing 1st image, Browser shows "Page1.html". I can reproduce this with any contact sheet. Using "SimpleViewer" works fine but isn't a workaround for me due to missing color management with Flash (wrong colors in Firefox on my super dooper high end display).
My workaround is duplicating 1st image...
