Real Time Event Photography - Real time pictures over WiFi SD Cards

So you take pictures for an event and want to show any new picture you took on a big screen immediately in real time? Here it is.

Support for real time WiFi SD Cards like eyefi, Transcend, FlashAir, ezShare, SHAREit, AirCard and any other WiFi SD card. Just choose a folder as usual. If any new picture is placed in the selected folder or sub folder, PictureViewer displays this picture immediately. So as long as you can reach a folder PictureViewer can display a new picture in real time. This is interesting for example if you are an event photographer. Just connect your WiFi SD card with your Mac, then choose the sharing folder and you are ready to go. Any picture you take with your DSLR will be shown within PictureViewer. If our Mac is connected to a beamer, the beamer shows and new picture you take on the big screen immediately. Very cool !



How to setup multiple photographers

- You can also setup one or more photographers. For example, if you have photographer A, B and C you can setup this folder structure:

Then just setup your WiFi SD Card accordingly for each photographer. (Photographer A writes to folder ./photos/photographer-a/ etc.)
Then just point to ./photos/ with PictureViewer, and it displays any photo from Photographer A, B or C.

Q: Does it also supports 32 bit?

A: Yes! This is a so called universal binary that supports 32- and 64-bit.

NOTE: This will be terminated by Apple. Quote: "macOS High Sierra is the last version of macOS that will run 32-bit apps without compromise. The Mac App Store will require all apps (including updates) to be exclusively 64-bit by June 2018."

So I think PictureViewer version v7.0.5-12 will be the last version that supports 32 bit.

Q: Where is the IR Remote Control support?

The version in the App Store does not support IR Remote control support. With IR Remote control you can go forward or start the slideshow. This is only available with the version outside the Mac App Store, because of a technical problem. (Apple does not allow it.)

Contact us if you need IR Remote control support.

Q: Can I enjoy my images in a window that stays on top while doing something else?

Yes. There is a button "stay on top". Then you can start the slideshow in windows mode, move and resize the window where you want it and start doing something else and enjoy your photos at the same time.

Q: Can I set PictureViewer as a default application for images?

A: For version 6.0.0+ it will not work correctly. Use the Setup and Installation procedure

Q: There is an error like: The docu­ment “YourImage.jpg” could not be opened.

"The docu­ment “YourImage.jpg” could not be opened. PictureViewer can­not open files in the “JPEG image” format."
[cml_media_alt id='1323']pictureviewer4mac-error-connot-open-jpeg[/cml_media_alt]

A: We don't know what the problem is right now. This seems to help, thanks to user Ivo H.: Some­ti­mes it happens, that error mes­sage appears and after few seconds, photo is opened. I have tried to place your binary in the fol­der with pho­tos and it works then .. I also noti­ced that there is path to fol­der in the bot­tom of the photo (next to con­trols , ..) and it points to app­li­ca­tion fol­der instead of fol­der when opened photo is stored.

Q: Where is the File > Open menu? (grayed out)

The program runs but in the file menu pull down the New and Open options are grayed out.  I can drag a photo to the open grayed out window but I can't do anything with it.  What am I doing wrong?  I was hoping to open a folder with a number of pictures in it.

A: There is no file open menu or such thing. Please follow the instructions in the "Installation and Setup" and "Simple Usage" section above. (Basically you just need to add PictureViewer on the Finder Toolbar, navigate and point the the first image you want to show and fire up PictureViewer.)

Q: How can I add PictureViewer to the Finder Toolbar?

A: Just hold down the cmd (Command) key before drag&drop it to the Finder Toolbar.

Q: How can I remove an Icon from the Finder Toolbar?

A: You can remove an icon as follows: holding down cmd (Command) key, dragging the icon away from the toolbar and then releasing.

Q: Does PictureViewer works offline?

A: Yes. Fully.

Q: Does PictureViewer collect any data?

A: No.

  2. Your website says that pictureviewer4mac supports jpg files, but every time I try and open one, it says:

    The document “ATT00086.jpg” could not be opened. pictureviewer4mac cannot open files in the “JPEG image” format.

    Any ideas?


    1. Can you send the file to me?
      If not possible preview with Preview. Do a terminal file command to see if it’s a true JPG FILE or not. Let me know.

  3. Problem: Can’t open images JPG files on OS X Yosemite.

    Solution: Hello, I’m not sure what the pro­blem is right now. Maybe the image file is huge (file­size).
    But I post your solu­tion you found here:

    “it is jpg file from android (samsung). It can be opened with any other app­li­ca­tion. I have tried open several other pho­tos, but wit­hout suc­cess. Some­ti­mes it happens,that error mes­sage appears and after few seconds, photo is opened.
    I have tried to place your binary in the fol­der with pho­tos and it works then .. I also noti­ced that there is path to fol­der in the bot­tom of the photo (next to con­trols , ..) and it points to app­li­ca­tion fol­der instead of fol­der when opened photo is stored. — Ivo H.”

  4. Hello, I’d like to know if PictureViewer can display new images as they’re added to the folder that the slideshow is using?
    My scenario, I’m taking pictures at an event using an eyefi card that will send the picture to the designated folder. I would like the new images to appear in the slideshow automatically, without interruption or the need for human intervention, so the attendees can see them in almost real time.

    Thank you for your time,

    1. This is a cool idea I also though about this before. Right now, it’s not possible, but I think it should be and is possible 😉 So I noted it down for future versions. Stay tuned. I write an update to this / your post here so I think you should get notified and/or just ask again later.

  5. Will this application open *.ORF files? That’s the image format my camera uses. Preview on my macOS Sierra opens them just fine, but I need to know if your application will as well. Kindly LMK. Thanks!

  6. Hi I have the app running in slide show mode full screen but when I am adding new files to the watchfolder, the new images are not be shown in the sideshow? I thought this was a feature?
