I realise time is limited but an idea for the future could you consider when generating snapshot also generating a JavaScript file containing a list for all the existing snrm.PNG files in the snapshot directory. Then in the webserver page you could have previous and next buttons that would use JavaScript to replace the "static" images with pngs stated in this javascript file. This would allow the webserver users to benefit from the snapshots. Obviously wouldn't just be limited to snrm - es, ses, CRC, speed would work the same way etc
Would it work in javascript which is client side rather than a server side language?
I was trying to think of an easy solution for listing all the files in the folder when I was playing with the history page. You would need some way of generating a list of snrm.png files in the folder that would be up to date depending upon which files where there. I was trying to avoid using a server-side language (such as php) to generate the list because not everyone may want to install php or WAMP/LAMP. You can perhaps see with the history page on the advanced web interface, that I started dabbling with AJAX but I can't see how that would work if viewing via the Internet either
Unless I'm missing something I don't see how getting DSLstats to produce a javascript file would work.
I think it would need a small program running on the PC to generate a list of all current 'x'.png files in the folder.
You could then perhaps then use something like JQuery to output the contents of list to a html page.
Ideally this program would output the list in something like JSON or XML format. If you had a JSON file, then you'd be able to use javascript to parse the data to html.
You'd still need to write the javacript/Jquery functions to be able to output the data though and these would need to be included in the source code of the html page.
If there was something that listed the relevant .png files to a text or JSON file, then I'd be able to use JQuery to write the functions needed to output to a html page, but even so that would require dev time.
Without using a server side language (or a separate program to generate the list) I couldn't see a way this would work in the current format on the existing inbuilt webserver just using something which ran on the client side.
