How to change e-card logo stamp?

[mr.bena]

Hi, I replace images/stamp.gif with my logo bearing the exact same name and format i.e "stamp.gif" but it doesn't work. Is there any alternate way of doing this? Is the e-card stamp is Coppermine's credential and should not be replaced?

Hi, I am not using e-card sending again, because it seems like using this facility, image is no longer protected. I mean the receiver can download the image and use it for other purpose. If there is a method through which the image sent is still protected, then I will consider using e-card option again... this is not related with my previous query, I should post somewhere, I guess.. But this is just to let you know my status.. thanx..

Have you considered watermarking?
