is this normal size for my images?

hi guys, so i am working on a racing game where my tracks are 1280 high and 1920 width, since is for retina display i need double the size right? so it becomes 2560 x3840, so i divided this into 16 pieces of 480x960 but each image is like 422 kb. and i have a total of 8 tracks so this is more than 50 mg, so my game is already at 80 mg, what really disturb me is that i see similar games or other games with better graphics, for example the new game "beyond dead" i see a lot of good backgrounds but it only weights 22.3 mb,,or the game like mario called leap's world, it has many levels but its only 10 mb.is there something i am doing wrong? i am saving the images as png.24. thanks

If you have no need for transparency in an image, save it as png-8. That'll save you some room.

sorry but what does no need for transparency means?

Transparency is when an image has a section that is invisible. So for instance, if you had an image of a ball, you'd want transparency so that there was not a white box surrounding it. If you're talking backgrounds, most of these shouldn't have any invisible sections, so change them to png 8s

If you have no need for transparency in an image, save it as png-8. That'll save you some room.

Even if the images do have transparency you can still convert it to 8 bit.

Transparency = transparent areas = invisible = see through = clear areas with no colour.

Use ImageAlpha to reduce the file size of your images:

hey one thing, i did try saving one image into 8 bit and it did changed the size a lot too, all my images tracks don't have transparency so do you recommended save it as 8 bit instead of 24, i just thought 8 bit was for those old games where images looks like made of squares, plus gamesalad say to saved as png-24. so i just transfer 2 same image, one as 8 bit and the second as 24 bits, and both images look the same on my iPad so i should had saved all my 120 images into 8 bits lol, i don't know if i should do it now.

use png-8. you're thinking of 8bit gaming systems

Transparency or no transparency . . . changing the file from 24 bit to 8 bit will reduce the file size.
