Problem With Saving Images In Photoshop :x

i made a lil image with a transperant BG and a drop shadow comming from the image, but it shows the drop shadow being 100% filled but it really wasnt



thats image,

ive never had this problem before :x

btw i did save as a gif

 

hmm so what exactly is the problem ?

 

thats what it was before i saved it, notice the bottem right hand corner its not just completely black,
but when i save it it is completely black

 

it's like that because it's saved as a .gif and not a .png

.gif supports either 0% or 100% opacity

.png supports 0% - 100% opacity

 

o ok ty

 

no problem ^_^
