Alpha showing as white in html5 using photoshop to export to pngs on firefox
works good on android and PC

tried turning the transparency to black and using the bBlackToAlpha setting, but it just shows as black as well

I have 6 images on top of each other with alpha settings

anyone can help what I might be doing wrong?

I has a similar issue with an Android app I created.

It was quite a while ago, so I'm afraid I can't remember all the details or what the cause was (apart from the way older versions of Photoshop handled transparency information in PNGs). I solved it though by using this extension http://www.fnordware.com/superpng/

Thanks for that Poloraul!

I was messing around and noticed that if I set SetSpritecolorAlpha(i,249) (NOTE:not 255) on all the images that they all seem to work now...
I'm not sure if it is because I had SetSpritecolorAlpha just for 1 image before I checked it in html5
Using this I was able to do it with the png export for PS normally without using websafe saves or anything.
