I am trying to use a symbol from an image and I can't seem to figure out how to make all the white in the picture transparent while leaving the colored part. This way I could put the symbol with something else on my web page. I have seen the option to make individual colors transparent with the optimization option, but for some reason it automatically thinks that my PNG picture is a JPEG, which doesn't have the color transparency options. So when I do change the optimization options to PNG and do the individual color transparency thing and then click optimize nothing seems to have happened to the image other than having (optimized) written after the name. I mean even in Microsoft paint I can make the cut image transparent and place it over another one.
