Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
It mentioned PNG-24 support index transparent, so iOS support this, right?
Yes IOS supports index transparency, but you need to do a search to find out the difference between Index and alpha transparency.
Put simply Index transparency relies on you selecting a color that is the transparent color, so everything that is that color in the image becomes transparent. Alpha is smarter than that, so it will make the canvas transparent, leaving the image in tact.
Its more complicated than that, but you'll have to look that up.
The best way is to try some images and see how they look.

This will allow you to have transparency in the image, and reduce the file size.

png-24 = millions of colors
The main trade off is file size. If you have a simple graphic with no more than 256 colors, then use png 8, else use png 24.
