Dear All,I am utilising a php to populate a page with images.
I have a variable that changes due to the item selected.
At present if there is no image present, IE displaya an ugly box, Firefox displays the alt text.
What code can I use to check to see if there is an image present, and if not leave the field blank?
Thanks in anticipation of an answer.

Are you using a database?
Assuming you are using a database, you can do an <i>if</i> condition and see if the record is either <i>NULL</i> or empty/blank ("". Those would be the first things to try.

Hi,
I'm not using a database for the images, can I check whether the file requested is null?
