Is it possible to upload a new image to replace an old one but keep the same file name?

I only ask because this image;



has kindly been put in a few peoples signatures but there's a really annoying strip down the right hand side that remains in the animation after UA's pic appears, I can take this out easily enough but it's a bit much to ask everyone to change their signatures again.

I was wondering if maybe SaRuMaN or one of the mods is able to replace the file if I upload an updated version?

Thanx in advance

ok once you have posted your image, go to edit page

I did realise you could change the attachment but I wanted to know whether it would change the filename of it as everyones signature links to that image, it still needs to have the link:

As I suspected I tried it with another pic and the URL changes, I think I need SaRuMaN's help for this one, where is he today??

Getting an entire new central heating system installed, what a day.

I can easily upgrade the picture for you, send me a copy of the new version of the image file and i'll replace the old one with it.
