Hi Tim,
no problem, will ping you on twitter as well just to make sure you get the notification
as for the lightbox: this is implemented using clientside JavaScript (and css). There are a lot of opensource candidates out there, most of them based on jQuery (that is no nogo for me as that then also carries the load of the jQuery framework).
The one you are describing is what JCE Mediabox looks like, for me that looks a bit 'outdated'. I have found this one myself that could be implemented:
biati-digital.github.io/glightbox/
So how this works is that you can manually add a (configurable) class name to the image (but also video / iframe) and then the JavaScript will handle the rest.
ochResponsiveImages will load the css and JavaScript and initialise the element with the (configured) class name on the page.
ochResponsiveimages could also be setup to add the class name to the images it handles on the page.
This would then be an additional feature to ochResponsiveImages making it a completer toolkit and givig you as site developer some powerful image handling options.
I have just done a quick scan of 'pure javascript open source image viewers lightbox' projects, the package we select here should be 'popular', maintained and 'light', so if you are able to also search / investigate or maybe provide me with some example websites that have a good lightbox implemented, that would be great.
As for the timeline. i have currently a 'big' update in the works where ochResponsiveImages will also handle non-image elements (e.g. a div) that have a css background-image set (like the fullpage images you see on my front page). I will be releasing that in September (will be on holidays the next 4 weeks and do not want to run the risk of breaking things when I am mainly off-line). So after that is released and we have a good JavaScript 'lightbox' I can start implementing that.
What do you think?
