Hopefully this hasn't been asked and answered, but I didn't see it mentioned in the past several months or in a site search.

I'm on the aforementioned iPod, which is running the latest software for iPhones, and I'm always logged in.

I can see photos in a lot of posts when on the iPod, but in many others there's just the words "Attached photos" and a paper clip icon at the end of a post, but No photo visible, either in the default mobile or full site mode. No problems with my iMac. The browser (Safari) puts no limits on attachment sizes.

Should I be able to view all attached photos on an iPod/iPhone? If yes, does anyone have an idea what might be blocking them?
