Alternate images?

[sdlangers]

i have a site that displays dynamic images whose src is taken from a database.

 

however, some of the image links are broken. is there a way to specify an 'alternate image' if the link is broken..

 

e.g. if an image called 'someImage.jpg' is missing or renamed, then i need a way to display a default image 'default.jpg' instead of displaying the standard red x that indicates a broken link

 

<img src="/path/someImage.jpg">

 

i also cannot check on the server side if the file exists or not, because sometimes it exists but its not a valid image - and its a large database, so i dont want to have to manually review them all.

 

thanks!
