Hi Guys,

I have tried adding the 'Hide / Show Component' action on an image when the control is equal to ''.
This works however the img tag is still printed in the html and therefore internet explorer 6 shows an image icon with a red cross.

Any ideas would be appreciated. Cheers.

Done this before panels where available I had placed a label with content type html and assign the "whole" image tag or nothing to it.

In these days it should be possible to place a panel first, the image on it and make the panel visible or not.

I would also check to see that in the Database the value of the field holding the imagefile name is indeed '' as opposed to '<Null>'
The first being a blank, wher Null actually is a non value.
The way to avoid this fast in MySql is to change the SQL to replace any NULL with a ''.

  
SELECT ifnull(imagefield,'') FROM..........  

That way you are sure to receive ''.
Another would be to change the Hide/Show to cater for NULL values.

Thanks mrachow I used your panel idea and it worked. I think that with php and mysql '' == NULL because the values in the database say null but i use '' in my equation and it works.
