I found a fix

make a plain canvas of the same size as the image

go to file-> place embedded

and place it

now you can edit it

I have the same problem, but I solved it with this method (I am using windows OS), first select the image/photo (which is couldn't opened in photosop), right click, open with Paint, when the Paint open good with the image you choose save as .jpg with different file name, after that, open the new file (that you saved from the Paint) in Photoshop, works for me hopefully works for you guys.

The thing is, I still have no idea, how to fix the "SOFn DQT...." problem permanently, its so exhausting when you need to open so many images in photoshop with that problem, if you guys have the permanent solution, please share, thanks

I guess it's due to the phone the photos were taken with.

my friend uses a very cheap phone and

idk if its relevant and mailed me.

It look all this images come from smartphones.

No one from my Sony or Canon get the same issue.

The easiest way that I found to solve the problem is losslessly rotate images back and forth in ACDSee and then no problems in Photoshop.

Shame on Adobe.

maybe this helps: (in my case it works)
so - go to the folger with your fotos - then mark all of them - then click the right mousebutton - then go to "SageThums" - and here click on "change to jpg" and then ... magic .. you can open the fotos in Adope Photoshop :-)
tell me if it works also in your cas! :-)

Only way round it is to open with irfanview and Save As...

Weird to note that it's happening:

a. with Whatsapp images i receive on my phone, which then I email myself to open on iMac. 

b. Images emailed directly to me from colleague's phone.

In both cases i dropped, as usual, the pics into Bridge, which then gave that same message when opening in Photoshop.

In all cases, dropping the images onto the desktop and opening with Finder, is ok, so the images are not corrupted per se.

On the other hand, I emailed a pic i took with my phone, to myself as above, and all went well (no third party smart phone & no whatsapp involved). 

Not sure whether there is any correlation. Maybe most of this info is irrelevant, however trying to provide as much details as possible maybe someone with deeper knowledge can help us get to the bottom of this

Same here, Adobe CC fully updated.  My colleague took pics with his phone and sent them to me via email, something we regularly do.  I CAN open them with Finder, no problem, so they aren't corrupted or anything.

But Bridge refuses them (no thumbnail), then Photoshop with that exact same message.

i have the same problem, working in a photoshop cc2014 in a windows8

Any help would be very helpful

No open photos
