flyingsuperpetis Posted December 31, 2007 Share Posted December 31, 2007 This morning, I noticed that a disproportionately large amount of space was being taken up on my phone by pictures. So, I blew away all the photos on the device, and after going through every image on my pc, and weeding out the fluff to leave just the essentials I need for work, I had a mere 80mb of jpgs on my pc to sync over. That's 80mb. I then sync them to the phone. Space taken up on the iPhone by 80 megs of images: 320mb. Does anyone know of a way of disabling whatever is going on here? On an already small 8gb device, I'm continually fighting for space, and this "feature" (whatever it is) is definitely not helping. It appears that iTunes is converting every jpg to an uncompressed png or tiff or something huge first, probably so the processor doesn't have to do as much work to decode the images jpg codec for display. ...Not only is it a waste of space on the device, but now on my workstation, I have the original files arranged in their folders, plus since iTunes only syncs images by the folder, I've got to have duplicate copies of the images in an "iPhone Pictures" folder to be able to avoid syncing over the entire folder, and now, iTunes creates another folder of its own on the workstation, the "iPod Photo Cache" which contains all these puffed up versions at roughly 4 times the filesize. Between the iphone and the pc, these images should be taking up 160mb. Instead, they're taking up 800mb. Not a good system. Link to comment Share on other sites More sharing options...
JSn1™ Posted January 21, 2008 Share Posted January 21, 2008 Yes, iTunes "optimizes" photos for iPhone, don't know what kind of compression is used. Split the albums and copy album by album and see which one is taking more space. Or maybe, that is the way the iPhone works. Link to comment Share on other sites More sharing options...

You are right and JSN1 is wrong. Photos are (unfortunately) stored in some sort of uncompressed bitmap format so they can be viewed fluidly with the iPhone's relatively underpowered processor. It's sad when you consider how little space is available. I discovered my photos are taking up about 400KB each on average which makes sense since they are also downsized.

Optimization doesn't necessarily mean less size... Link to comment Share on other sites More sharing options...
