Yahoo Mail users are getting 25MB attachment limits and easier photo uploading, a new Messenger beta allows for full-screen video chat and social network link-ins, and searchers will get refinement and analytic results as part of Yahoo's big Monday announcements.
The big thing that everyone will find use for is an increase in Yahoo Mail's attachment size limits from 10 to 25MB. Multiple photos and images can now be selected for upload, and rotated and previewed before they're sent. Yahoo's also allowing Mail users to hook in third-party applications like Flickr, PayPal, Picnik, Xoopit and ZumoDrive, and adding a consistent header to all its applications. These features, available in "New Yahoo! Mail," should be rolling out to all users shortly.
Messenger actually has a whole new app out, one that allows for full-screen video chat and a side-panel Updates view that shows what your contacts have been up to on Flickr, Twitter and other web spaces. The beta, for Windows only, is a free download.
Finally, certain Yahoo searchers will get results that all for both filtering by topic/subject, and contextual follow-ups when you search one term after another. As Yahoo explains it, if you search for "cat" and then "jaguar," its engine should know that, based on the "cat" search, your "jaguar" is much more likely a creature than a luxury vehicle.
