Hey Photoshop experts!
 

How can I turn the following gif into a 1x823 file that would be used as bacground image for my html page and give me the same backgound when viewed?

Aslong as there's no gradient in there


open the image in photoshop then

image >change canvas size
to 1px wide.

then
edit> define pattern

create a new doc 823*1 and then fill with pattern.

save that as your background

Try Filter-> Pattern Maker for best results :thumbsup

Thanks for your help guys! :thumbsup
