before putting them onto you iphone, try using something like Microsoft Office picture manager to either rescale/crop your picture to iphone's screen size (480 x 320)

yea I did converted my pics to 320x480. But still no luck. Help

Like with the iPod, iTunes automatically downscales your photos so they take up less space. You'll notice a folder called "iPod Photo Cache" in your pictures folder which contains the smaller ones.

If it's the same as the iPod you should be able to select iPhone in your device list when the iPhone is connected, go to the "Photos" tab, then select "Include full-resolution photos."

Another reason is the FS format. NTFS doesn't agree to well with picture transferring.

Try moving your pictures to a fat32 device such as a flash drive or ext HDD and add that folder to iTunes, then sync.

This is what I had to do and the resolution issue went away.

i am still having that same issue regarding crappy resolution of pictures. i tried putting the folder on fat32 drive and still no luck. by the way in itunes there is no "Include full-resolution photos." check box to select from. looks like ipod is different than iphone. please tell how can i transfer full resolution pictures on iphone. that crappy itunes downgrade my pictures resolution automatically. is there any other option. plz thks.

NTFS vs FAT32. If that were the problem then it means if you had the same photo copied to both file systems then did a binary compare they could be different. I don't think so -- not much world work if a FS meant files were altered.

I emailed a photo from my iphone to myself and I believe I recall the photo I got in the email was 640 x 480. itunes downscales to that, but I've heard it will also upscale a small photo also to 640 x 480. This is why some folks have complained that the iphone images actually take more space in those cases. Of course any time it applies a transformation you risk quality loss.

It would be nice if you could do the transformation yourself in such a way that itunes says "well that's fine as-is". Worth some experimenting.

ok now i just transfered a picture file from my pc which was 1.44 mb pictuer in size and after the transfer itunes shrinked it at 640 kb file. so u can see the difference in size. i want that the file size remains the same as well the quality. please tell me how can i put pictures thks.

I suspect that even if you used a hack to get a larger image file on the iphone it wouldn't work correctly. I've noticed the behavior in all apps seems to suggest a relatively slow CPU, but a fairly powerful graphic processor. I think Apple wrote the apps with this in mind and leverages the graphic processor to help as much as possible. I suspect the CPU has access to an image buffer limited to 640 x 480 and the CPU _never_ scales. But the CPU can ask the graphic processor to scale how it shows the image buffer to fit the display. This would explain why they are willing to waste some flash memory by _upscaling_ very small images up to 640 x 480 so that the CPU won't have to do so at viewing time.

That will only make it worse. iTunes scales whatever largish image you put into the phone into something more manageable, 1024x768 ish. You can still zoom in quite a bit on the iPhone screen so it seems like it is much higher than the native screen resolution. I don't have a problem with this as it allows me to carry thousands of photos I couldn't carry otherwise and it still allows me to zoom in quite a bit. I don't really see a need for having 8MP+ images on a phone with a 480x320 screen though? They look razor sharp until I pinch it in a few times.

I guess i should go deeper into what I was getting at, as my pictures work ald look great, and others don't.

What OS are you using iTunes under, and what exactly do the pictures look like?

Maybe this?

If not and it actually just looks like garbage, then pardon me from thinking outside the box.
