After the release of Barracuda Opera uses the <link rel=”icon”> or <link rel="apple-touch-icon"> meta in the site's header to find the logo, but it will only show in Opera if the attached image is wider than 114px. In stackoverflow's case the code looks like this:- <link rel="apple-touch-icon" ...

Facebook uses a proprietary link type called image_src: <link rel="image_src" href="location/of/image" /> Just insert that in your <head> and Facebook should be able to pick up on the image. If you're also interested, Facebook also recognizes two other rel values: audio_src and video_src. See here for more.

Can't miss the holy grail of video systems, FFMPEG. It does just about everything you might need to in online video--take in multiple formats and convert to another, thumbnail, etc. A heavily modified industrial variation of FFMPEG is what allows YouTube to work the way it does. Here's a quick command line tut for thumbnailing: ...

You can't control this, Blogger decides for itself which image to use. I did some reasearch a while back (documented here), and concluded that it's most probably the first pictures in the post which is both over a certain size, and hosted in your own Picasa-web-albums / Google + Photos albums. From memory, I think that testing showed that the size ...

Do a "on-mouseover" thing, where hovering shows a lightbox of a larger image. You can customize how large the image is that pops up, and how the effects play out: moving the mouse away makes the image vanish immediately, or fades out?

Google Blogger does not have such features. You could write a lot of complex Javascript and ajax to actually parse each post and create a thumbnail for each one that does not have text. I think your best bet is to take advantage of the tagging feature. Tag posts that belong in gallery with the word "gallery" then simply make a link in the template to do ...

Hello good guitar songs lover (yeah, Django Reinhardt rocks). I don't think you can implement that gallery directly on blogspot. I have 4 blogs (don't ask me why so much) on blogspot, and I've never found such feature but I got an idea. Your friend can use flickr to make his galleries, and then use its galleries feature to embed into blogspot. The problem ...
