Serving GIF as a JPG

[Insomniak]

Hi, hope this is the proper forum,
Im really not sure how this might be done.

I have a JPG banner hosted on my site for hotlinking and would like to replace it with an animated GIF keeping all the links active with the JPG extension.

Is that possible through .htaccess or something?

Thanks

something like this might work to internally rewrite all /path/to/file.name.jpg to /path/to/file.name.gif:

Options +FollowSymLinks
RewriteEngine on
#
# internally rewrite .jp(e)g to equivalent .gif
RewriteRule ^(.*)\.jpe?g$ $1.gif [L] 

you would normally prefer not to use the ambiguous, greedy and promiscuous '.*' in your regexp, but i didn't see a good way out of this one.

Hey thanks,
it's actually only a single file I need to do this with so I assume I can just put the filename in and not even use wildcards.

you definitely want to be as specific as possible with your regular expression.
maybe like:

RewriteRule ^banner.jpg$ animated.gif [L]
