InDesign won't recognize PNG files, can't "Place"

[timothyl85839792]

I created a document about a month ago, a catalog, and placed PNG image files into image boxes for the layout. I opened the file back up today to do some edits and all the sudden InDesign tells me I have broken links. I investigate further to find that the images are located where they are supposed. I tried to "re-place" the png files into the boxes but InDesign doesn't recognize it and won't allow me to place it.

For reference, I also tried to open in PS but it doesn't recognize it either, so I'm sure it's a file issue.

Has anyone run across this and can you advise?

I had this issue with InDesign Ver 182.1 x64 with winows 10.  My only option was to resave the offending .png file in fireworks using "Save As = Flattened PNG" format.  This allowed Indesign to open without issue after I relinked the file.

To determine the offending files was difficult as the InD gives no idication which files were the problem.  To solve this I moved my linked files to a new folder and executed a manual re-link on each file.  The >PNG that were OK relinked fine.  Those that were "Cannot place this file, Invalind PNG..." were now easy to identify and I resaved as PNG Flattened

I hoep this helps Win users
