[BUG] After Upgrading a Site to 2sxc v19.03, Image Paste Fails for PNG Files

[jeremy-farrance]

Bug Affects...

[x] edit experience / UI
[x] admin experience UI

Current Behavior / Expected Behavior

With the Patron feature enabled so you can paste images in the Edit UI, this feature stopped working in recent versions. Not sure when, but I noticed it right after upgrading from v18.6.1 to v19.3.0.

Things that still work:

• I also tried downloading the image to a file on my local machine and then drag n drop. That worked. So this is specific to pasting an image from the copy (buffer).
• I also tried the same thing as in the video, copied a JPG. That worked. So this is specific to PNG files.

To Reproduce (Steps, Videos, Screenshots, Apps)

I included a video to carefully demo the steps to see the problem.

The error makes it look like the problem might be ImageFlow, but that is not the case, instead, 2sxc is writing a 0 byte image as you can see here (multiple attempts shown:

Your environment

• Hosting platform: IIS
• Ui Languages: any/all

UPDATE: I found another site running 2sxc v18.6.1 on DNN v9.13.07 with the Patron feature enabled, and the problem is on that version also. So its been like this since at least 18.6.1 and possibly earlier.

so it does need patrons enabled...
...but it does sound like something is broken, but I believe we didn't do any changes related to this.
we'll research, thanks for the report.
