Q: Lines on imported photos

I'm having the same problem. This happens on iPhone, iPad 2, iPad Mini.

I've tried from different SD cards, I've tried from different cameras, it's always the same.

Are your iPhone and iPad both using the same iOS version?

I'm seeing the same thing but not on every photo. Just about half of the 360 images I imported tonight have this issue which I have never seen before. My iPad 4 is on 9.3.1

I had those same artifacts, starting with a recent iOS update, on my iPad (4th gen).  I installed the new update 9.3.3 this morning and it appears the problem has been fixed!

It seems I spoke too soon.  After a full day of editing and transferring .jpgs to my iPad, the short horizontal lines on one edge of the photo have returned in two of my images .  All the affected images that had already been on my iPad just prior to my 9.3.3 update display correctly now, but apparently something in the process of transferring photos to the iPad introduces the artifact problem.

Same problem here. Not solved with 9.3.3 update. If I was suspicious I'd say Apple has either become incompetent or is deliberately making older iPads like my iPad 3 unusable. Mine also freezes up for 30 seconds or so regularly and restarts occasionally. But I suppose it's just that their quality control is now awful. Too many upgrades and not enough time spent on debugging. Thus one is really annoying and means my iPad is no longer usable to save pictures to.for me every imported picture is affected.

Stranger and stranger - imported picture on FB still shows lines. But pictures once synced with iCloud  and in Photo Stream lose the lines! Very weird.

I wonder if it is limited to photos we have edited. I don't have the original source batch to check. I will have to do a test.

Usually I am uploading photos directly from my camera but in this last time they were all JPG converted from RAW using Photoshop, and a number of them were edited, i.e., cropped, and I made overall and local adjustments in ACR. I'm wondering if it was limited to the edited photos.

Will need to do more testing but I am interested to hear from others, too, if the ones affected had been modified or were straight out of camera.

MIne were straight from camera

I have suspected this, too.  I've only transferred edited photos to my iPad, and with these the artifacts don't consistently appear.  I have had "broken" images suddenly correct themselves (after updating to iOS 9.3.3) but I have since had more images display with the lines after updating.  I use a (home) network file viewing app to move pics from my PC to my iPad (no iCloud).  This morning, I even had an image transfer to my iPad fine and I posted it to Facebook with no issue.  Later, I went in to Photos to view it and the lines suddenly appeared!  The only thing I had done in the interim was to increase the screen brightness on my iPad for easier viewing, though I can't believe that caused the problem to appear.  Lastly, I've seen the lines on images I've posted to Facebook and texted/iMessaged to others but I don't believe I've ever seen one of these images display incorrectly on Instagram!  If I had to guess, I'd say it has something to do with image compression incompatibilies between editing and display software (.jpg algorithms being handled incorrectly).  Lastly, not sure if this has been mentioned but I believe the artifact lines are all various shades of grey - none are in color.  I need to double check on that...

IF I open the affected images in Snapseed then no artifices are visible!

From my iPad, I just emailed a corrupted image to myself.  Within the Mail app, it displayed correctly.  When I opened the email attachment on my PC, it displayed correctly there, too.  I think the problem is in the Photos/Camera Roll app on the iPad.  And I suspect other apps (i.e. Facebook) that can pull high-quality or even original-quality images from Photos are just passing the problem along.  Perhaps they're relying on Photos' compression and not compressing further so the lines persist.  I'm not familiar with Snapseed, but I've not seen the problem with Instagram and I'm pretty sure Instagram compresses images a great deal.  Maybe apps that apply their own (high) compression to uploaded images eliminate the artifacts in the process?  After all, these erroneous lines can't be more than 1-pixel wide...

Here is a sample corrupted image:

and here is the same image, but I first further compressed it before transferring to my iPad:

The first image was > 2.8MB .jpg as transferred to iPad.

The second image was < 1MB .jpg as transferred to iPad.

All of my edited pics, after .jpg conversion, are typically 2 - 3MB.

That I can transfer the same image to the iPad at 2.8MB (lines appear) or .8MB (no lines appear) with different results seems to point to .jpg compression/display issues with the iPad for file sizes greater than some "x" megabytes...
