Hello,

I want to display an image in Javascript from a folder which is named after a record 'id' and the name of the image is prefixed by X_

I have made the following guess as to what this might be - please can you correct?
<img src="travel_pics/" + id + "/X_*.jpg" width=150 height=100>


Many thanks

If there are more then one files that match the wild card then which file should the browser display?

I will ensure that there is only ever 1 file that is prefixed X_ in each folder.

Sorry but even then, JavaScript cannot look at web server side file system.
Browser is allowed only to ask for one file and gets that one files as response.

You have to script that on web server side by ASP, PHP or whatever scripting you use on server side.

It shouldn't need to look at the web server side file system - because the filename is composed of attributes already available in my PHP script - namely the 'id' that are alredy being displayed on my site...

Really all i'm asking is how to use a wildcard in a filename:

"/X_*.jpg"

whether that be
"\X_" . * . ".jpg" - will the asterix work here ?

My bad!

Since there is only ever going to be one image in a folder that is prefixed X_ i may as well give the image a complete name e.g. XXX.jpg and do the same for all folders, that way there's no need for a wildcard anyway.
