hi, i have a little problem re: img and dtml-try tags: there are images stored on an external server - these are named after student's universtity usernames e.g. lreilly.gif. represents moi, lee reilly. the problem is that it is not guaranteed that such an image is stored for *every* student so i want to do something like... <dtml-try> <img src="d:\<dtml-var uname>.gif" width="240" height="180"> <dtml-except> <img src="d:\dilbert.gif" width="240" height="180"> </dtml-try> i.e. if the student gif exists display it otherwise display the file dilbert.gif. if the files were stored on zope then modifying the <img> tags to plain <dtml-var uname> would work fine except that (i) they're not stored on my server (ii) <dtml-var uname> would display the username and not the image (id=username) - i think this can be overcome though. is there anyway to adapt the above code to actually *throw* an exception when the image is not located. the results of the above code are as follows: if the files exist => it is displayed if the file doesn't exist => nothing is displayed anybody have any thoughts / advice? cheers, lee -- Lee Reilly mailto:lee.reilly@ntlworld.com http://www.footkick.co.uk
