After updating to El Capitan, all of the photos I added to a project that I was working on goes black when reviewing the video.

So far there hasn't been a solution to the initial posted problem "After updating to El Capitan, all of the photos I added to a project that I was working on goes black when reviewing the video." nor an acknowledgement by Apple that there is a problem that may have been caused by the El Captan release.

I have sent two feedback messages to Apple and also assume that someone from Apple monitors the community support discussion Web site for bug reports. We have been posting on the iMovie Apple Support Community for this problem when perhaps we should also be posting on the El Captan board since it appears this is an operating system caused bug.

In any event, I composed a letter yesterday that I send via snail mail (US mail) to a high level Apple executive (not the CEO) asking for his help in directing the problem to the appropriate engineering group. Hopefully his assistant will forward it to someone to respond to me. I would be surprised if the executive acknowledges receiving my letter. I am on the East Coast U.S. so the letter may take a week to reach California.

Stay tuned.

Like all the other's on here, I had same problem after upgrading to elcapitan. Imovie will not display still photos unless you convert them to a movie type file like MP4, and that is a lot of hastle, you need a program to convert them. I have spent hours to make a short video of still pictures. this used to take minutes with the old system. ive given up on imovie now and got "MOVIE EDIT PRO" from the app store and it works a treat. its free to try, but leaves a watermark on you movies, so i purchased the full version. its not expensive. but it grieves me to have to pay for something that i could do for free until apple upgraded there system.... or should i say downgraded..

iMovie 10.1.1 has mostly corrected the still photo problem.

It appears to me that iMovie 10 works the same as MOVIE EDIT PRO.

iMovie 10.1.1 has mostly corrected the still photo problem.

Geoff, does this hold true for El Capitan?

Yes, it was El Capitan that was responsible for the problems with iMovie 9 and earlier versions of iMovie 10. I said iMovie 10.1.1 has mostly solved the problem since I have seen a couple of posts about problems with still photos with 10.1.1.

I had this problem too, seemed like the only quick reasonable cure after reading this thread was to upgrade iMovie to the latest version. I was running iMovie 9 for years, then just did the El Cap upgrade and my images went blank. After upgrading iMovie to the latest version (10.1.2) this problem has gone away and its working again. It's a different version of iMovie I feel, some changes I like and some I do not.

One thing I noticed right away is you can no longer do a custom EQ in the audio section. You have to pick from their Equalizer presets and it doesn't appear you can modify any of them. Most people will be okay with this but it might bother some who liked to tweak their own audio EQ with the little bar sliders. On a positive note it appears the interface is a little more user-friendly, but perhaps with some loss of features. Rendering video (Share/Export) seems to be a little more idiot-friendly with less dialing in the export settings, again some may like this and some may not. I'll have to use it more to see what else is gone/added but for now I'm glad to have my images back without having to do anything else, a small price to pay perhaps for just having the upgrade fix the blank images and not needing to do too much tech tweaking. Thankfully it appears the latest iMovie is largely unchanged, I was especially glad to see my iLife audio effect files and jingles still available in the new version as that was one of the main reasons I chose iMovie in the first place, for professional background sounds.
