Unable to create large image file in iphoto

I make a lot of panoramic images by stitching together overlapping images with hugin in TIFF format, then edit them in iphoto and use it to export them in jpeg format for greater versitality of use. So far I haven't had any trouble, even with large images as big as ~25,000x2000 pixels and ~90MB file size.


However, I have come across a problem recently trying to export an edited version of a particularly large one - 38,062x1799 136MB file size. I can export an unedited version to jpeg without trouble, but when I tried to export an edited version it gave me an error saying it couldn't create the file. I looked around here for solutions and found the suggestion to check the file size in finder, it was zero. After experimenting I've found that the file size goes to zero as soon as any changes are made to the file, the edited image can still be viewed in iphoto, but does not display if you try to zoom in. I have tried making the TIFF file again with hugin to see if it is a problem with the file, but I also experience the same problem with the newly made file.


I am working on a Macbook air (1.7 GHz Intel Core i5, 4 GB 1333 MHz DDR3 Memory, Intel HD Graphics 3000 384 MB, Version 10.7.5 OS X) in iphoto '11 version 9.2.2 (629.40). Any suggestions for getting round this issue?

MacBook Air, Mac OS X (10.7.5)

I thought of something that might help with working out what's going on.


After I make any edits to the image, if I move on to the info tab the image initially goes a bit blurry as it often does with large images, but instead of coming up as a clear image after a few seconds like normal, I get the image I've attached here and the file size changes to zero. To be able to see the thumbnail of the edited image I need to come back out to the library again, but the file size is still zero. If I revert to original the file size is restored.User uploaded file

I recall someone discovering a top limit of about 50 mp for an image in iPhoto a couple of years ago, but can't be sure.

Export the image to the Finder.

Make a new Library -

Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'

Import the image to that and try edit it. See what happens.

Don't think that limit is still around. I've just imported a 582 MB image, a Photoshop file, into iPhoto without issue. Well, there is one small issue. When I double click on it to view in full size I get the ! warning for a few seconds. It take a while for iPhoto to render the full 582 MB image. But it eventually does. When I go to edit it the SWOD appears for a while also. It one whopping big file. Took about a minute to export as a jpeg (with 8 GB of RAM).

Sorry, been busy the last few days and didn't get the time to look into this again, I tried that and it didn't work either 😟 I have also come across the same problem with another image, this time it is 33220x1589 (~53MP) 113MB file size, I noticed I was maxing out my processor so I suspect it might be a hardware issue, I'm going to try it on one of the more powerful macs at work on Monday to test that theory
