Photoshop CS5: Opening Indexed Transparent PNG loses transparency
Opening a transparent PNG causes the transparency to be lost, and turn into a black background and with an Indexed Color Mode. This happens when I save the PNG from Chrome and open it in Photoshop. Same issue when dragging it from Firefox 5. Pretty sure there is a work around for this, but can't remember. When dragging from Firefox, it does keep the Alpha channel, but am still having issues getting the BG to be transparent like the original. File is here:
Edit: I finally got it by selecting the alpha channel in the file (the one that I open that has a black background), and I just filled the selection and deleted everything else. Not sure why I can't simply open/drag the file while maintaining the way it looks in a browser or Windows.
Edit 2: I was only able to do this by Dragging from Firefox into Photoshop. That's the only way I was able to open it with an Alpha channel.

2) Photoshop opens transparent PNG just fine, but cannot currently open indexed color PNG files that have indexed transparency -- because it just doesn't fit with Photoshop's image modes.

I used the pixlr (an online, simple and free image editor) to simply open the file, and save it again(it opens the image correctly, and offers the option to save in "png full quality" which saves the image with the correct transparency! Now, just reopen it in Photowhop and everything is ok ;)
ps.: weird that an online tool, made in flash, can open it and photoshop cannot!
