nol33t, are you coding this for 1.3 or 1.4? Or would it work with both?
1.4, but a downgrade wouldn't be too difficult imo (could work without other changes on 1.3, i'll try).
and actually..here's the mod attached

I added as you suggested:
- on the tooltip the number of pictures left
- arrows disappearing when you're at the start or the end of the filmstrip
- internationalization ( english.php, a new array $lang_film_strip )
last demo still
hereI tried a lot of different implementations ( cause there was many different solutions to do this ), and the one i'm submitting does work with IE/Mozilla browsers, and is the most comprehensive i manage to found out ( at least for me

)
Basically, here is how it works:
- when the template for the filmstrip is generated, it adds in the html a comment tag <!--STARTPOSX#X'#X''#X'''ENDPOS--> where X, X', X'' and X''' will be the new "positions" if you click on one of the buttons:
- X for fast rewind ( pos - number of thumbs set up for the filmstrip in the config )
- X' for rewind ( pos -1 )
- X'' for forward ( pos +1 )
- X'' for fast forward ( pos + number of thumbs set up for the filmstrip in the config )
when you click on one of the buttons, it will call a javascript script which will parse this comment tag, and depending one which button you clicked on, send the new position to display, with the album infos, to filmstrip.php, which returns the new filmstrip. Since i use the display_film_strip() function to do that, the new filmstrip will contain the new <!--STARTPOS ENDPOS--> comment, but with the new positions ( so it loops which i kinda like

)
the only probs i found are:
- the html code i added in $template_film_strip does not validate as XHTML 1.0, but i'm not that sure displayimage.php was before, and those are minor things to fix, and i'm must admit i'm not good at that ( which does not mean the html is real messy )
- one glitch when you're at the beginning of the filmstrip, arrow takes two clicks to dissapear, if a math geek looks at my code i'm sure he'll find the prob in 2 sec

)
- last but not least: you all work too fast on the devel 1.4 release, i had to merge my mod!

If you want more explanations on my choices for this mod and its implementation, just ask
Hope you'll like it,
