is it possible to make a photo and have him saved on lets say 8mpx and 2.4mpx together?

It's not possible to add 2 pictures together at all, if that's what you're asking. It's possible to make one picture out of them with a "photo montage" app, but what you get is the same as if you printed them both, put them next to each other on a table and took a picture of that. (And the resolution of the montage couldn't be better than 2.4MP, which means that the 8MP picture quality suffers. An 8MP per picture montage of a 2.4MP picture would require creating the missing pixels in the 2.4MP picture - and you can't create data that doesn't exist. [An 8MP montage of 2 pictures could have a maximum resolution of 4MP per picture <half of the 8MP picture>, so you'd lose quality on the 8MP half and have artifacts created on the 2.4MP half.])

Now if you're talking about saving the picture twice, once as 8MP, then again as 2.4MP, sure, but the camera would have to be mounted to something solid, the object you're photographing would have to be stationary and, for best results, you'd have to trigger the shutter remotely (so you don't move the camera between shots). Set the camera for 8MP, take shot and save it, change it to 2.4MP resolution , take another picture and save it.

Is it possible to take one picture and have it saved as both at once (actually it would save one, then it would save the other - even a computer can't do 2 things at the same time, even though it can switch back and forth fast enough that our slow human senses think it is)? It could be done, but I don't know of any app that's been written to do it.
