I've got the Opera Mini beta for the Pearl. Does anyone else have this issue: you know how usually, you can scroll to a picture, and it'll automatically give you the option to save it? When I scroll to it, it won't give me that option - it just highlights the picture. Anyone else have this problem?

Yes, I see the same issue. I think that the photo manipulation feature was dropped for 4 beta. You may send an email to Opera to ask about it or request the feature.

OM 3 did a nice job with images. You can run OM 3 along side OM 4b if you really need that feature.
