I have a highlights page that refreshes the images every X seconds which works fine. These 6 stills are clickable which opens them in a new window, but i find the image is a cached version at times, what would be the best method making them reload completely once opened??

below is part of the main page refresh code i use, which is working great And i add that into the page which refreshes fine. But the clickable image sometimes loads a cached version instead of the refresh/reloaded version.
How could i fix this little issue, I know it's something really really simple!!!
Pages address is http://www.users.on.net/~ace2/highlights.htm if needed

My php code to solve this issue

Add the timestamp to href

Code: Select all

$image_timestamp = timestamp("image.jpg");
print ("<div align=\"center\"><a href=\"image.jpg\"><img src=\"image.jpg[b]?$image_timestamp[/b]\" height=\"85%\" alt=\"Latest picture\" title=\"Latest picture\"></a></div>\n");

Will php work with my HTML, my ISP doesn't allow/uee php according to there personal web space section...

It should be possible to do something similar with javascript.
The line "img.src="7am.jpg?rand=" + Math.random();" in your refreshImage function does it.

Try...

That line updates the page images, but not the link ones opening in a new window.

<a id="lnk1" href="7am.jpg" target="_blank" ><img src="http://users.on.net/~ace2/7am.jpg" alt="7am.jpg" id="im1"></a><span style="color: #1A20CC">TAKEN AT 7AM</span>

Thanks, I'll give that a go
