Thanks for the info, could you tell me if this could be done without ssh? just using manazaa? (i dont have wifi)

Thanks, btw. very nice to know

Hi, glad you found this of some use, and to answer your question, I believe manzana should be fine. You're just doing file transfers to that specific directory, just like uploading a new skin per se. You do not need to apply permissions to the files btw, so again, manzana should work just fine.

this has been bothering me ever since i got the iphone.:angry:

i really find all the "jailbreaking" and manza stuff kind of hard.....do you guys think apple is aware of this issue??? , has it been mentioned for a future update??

and why does it do that????:angry:

I'm sure apple is aware that their iTunes is downsizing the pictures, it's probably to conserve space, especially for people with 4gb iPhones. Unfortunately Apple tends to impose a way of doing things on it's users and eventually open up more room for advanced users. My guess would be that a future iTunes update allows us to set the compression level for not only Audio, but eventually Photos too.

Until then, get used to jumping through hoops :P

4- Fire up your iPhone, goto Camera Roll and find your new addition in all it's glory
BTDT, waste of space.

The iPhone apparently takes snapshots of photos in the camera roll, and uses it when displaying images. This "snapshot," if you will is apparently around 640x480.

It doesn't make any difference whether you add a 3000x2000 photo, you won't be able to see all the detail on the iPhone--not even close.

If you saw an improvement with this the placebo effect is alive and well! ;)

Here are a few comparison shots:

Then my only consolation is you've wasted just as much time as I did ;)

I kidd..

I'm going to test the placebo affect for myself with some pictures pictures that clock in at 3 megs each. Will post my results in a bit.

You're right. Here's some info from Tansee Transfer support, when I asked them about retrieving higher resolution pics from iPhone:

"Hi,
The photos stores in iPhone is re-arranged, they are not in ori-resolution.
So any app can't retrieve full size, :)"

iPhone can't display pics at full resolution, period. That's why they can't be retrieved either.

Placebo still gives you a 34% "fool-yourself" effect.

What about pics in safari?

I haven't tried browsing to a local directory yet, if it's even possible.

Hmm... it's automatically parsing an http:// prefix. I'm willing to bet the mail app won't hotlink a local url that doesn't start with http bleh.

Alright, some time has passed and I've had a go with images in safari. Maybe you can help me here because I think I'm seeing the full resolution, but now I'm not sure. I reckon I'll have to download the image and sync it to find out.

Here's the image I'm using, browse to it from your iPhone:

http://i45.photobucket.com/albums/f63/abadip/Cat-AddisonSiameseMix.jpg

I'm able to zoom up to his eye to see the type of radial lights they used when I view it through safari. When I sync the image, there is a level of quality loss. I can't see the difining lines in the light reflection in the eyes. They don't look like flowers as they do in safari, but as rings in the photo app. Additionally, I'm not sure if the image is the same dimensions, the only thing I can see the difference in is compression thus far.

So now this begs the question, how then do we launch local html files? Has that been figured out yet?

[geordisjd]

I don't think, in fact I'm sure Safari doesn't display pics at full resolution. They just look good on a tiny screen. I have pics on my .mac site that are 6,000x1,400. They're panoramic pics. And others slightly less ambitious. There is no way that they're are full resolution on the iphone. They will display at only 25-33% of full size on my 30-inch screen.
I can also display pics directly from my MacPro using iPhone Remote and open any pic on it with Safari. The same thing happens. The resolution is limited, I would guess to the same degree as the online pics.

Now I just noticed that Safari actually displays the resolution it uses right at the top of the web page. A +/-3,000x2000 pic on my HD is something like 586x368 on Safari. The numbers were there all along.

When I copied this photo over from my iPhone to iPhoto it came as a 4x5-1/3" 300 res 1200 x 1600 photo. Not 640x480. (I had to make it that size to show it here - but it's in my iPhoto library at the larger size.)

I don't understand what's being said in this thread.

PS: This picture was taken at a beach in Corfu, Greece just a few days ago.

Yes, it is one of the great mysteries of life: iPhoto will display iPhone-taken pics at 1600x1200. I'm not sure of it's a real resolution or a digital enhancement. My guess is that is a computer "trick" since no file greater than 640x480 can be retrieved from the iPhone.

The camera does indeed take genuine 1600x1200 pics.

However, they definitely are not displayed on the iPhone at 1600x1200, even when zoomed all the way in. I think I can put this to rest with a few sample images, all derived from the same photo, taken with the iPhone. That photo is attached (Edit: too large to attach).

The first image below is a crop of the original photo, to match what was seen on the iPhone. The second image is a screen capture of the iPhone showing that photo, within the Camera app, at max zoom.

You can see that the crop shown below (first image), has more detail than what the iPhone can display (second image). Plus, in order to match what I saw on the iPhone's screen I had to crop out a 267x398 section. Had the iPhone truly zoomed in to 1:1 it would have translated to a 320x480 crop. This is why the iPhone image is larger: it is displaying 267x398 pixels on a 320x480 grid.

The final image is a screen capture of how it looks on the iPhone when transferred to the Photos app and viewed--max zoom again. When viewed in the photo app--this after the iTunes conversion--the image seems sharper (with perhaps a touch less detail; hard to tell since the Camera app apparently smooths images).

I have obtained the full-sized images from the iPhone by connecting to it like a regular digital camera from my Windows XP laptop.

The process of transferring photos to the iPhone does lead to larger resolutions than 640x480 sometimes. I have two very wide images that were done using digital montage of multiple pictures into very wide photos. One of the two is made by splicing three pictures together and the other by splicing two. To my surprise, both were loaded on the iPhone! I'm attaching a picture of the iPhone while displaying the wider of those two pictures. In this shot, you see the picture as displayed in its full width on the iPhone. If I double tap, it zooms to the full height of the picture and I can then slide it from left to right to see all of it. Sorry for the quality of the picture but it's taken using a low quality mobile phone camera.

Sooo, it not a solution to the original problem of finding a way to store images in full resolution on the iPhone, but it's an interesting data point. If an image is wide enough, it is not cropped to something close to 640x480. It seems like it can vary (sometimes A LOT) depending on the dimensions of the original image.

I found that PDFs don't get compressed, but they're a bit slower to scroll/zoom. I wonder how big PDFs the iPod Touch can handle.

Yowza, my PDF is 15MB. I need to compress it more. And find a mailbox to use (I don't like to check my email, in case I lose my iPod).

hi all..

Nice to came across the good informative place...
