"After Capture Tasks" are limited to "Copy image to clipboard" and "Save image to file" but, when I open a saved image with ShareX, the image is automatically uploaded to imgur.
Is there another setting to prevent this from happening?
Opening ShareX with file will upload that file. You can disable uploading in whole app but if you don't want it to upload why you open ShareX with file?
I was opening saved images on the Desktop. The steps were right-click "someimage.png" on Desktop > "Open With" > ShareX.
By doing that, the image was uploaded to imgur which was totally unexpected. I wasn't intending on uploading the image.
You can disable upload app wide like this:

Now Upload->Disable upload not allowed.
What is the way to configure what to do on "Open with..." ?
Upload is really unexpected behavior as for me. Image annotate or view is much more appropriate, isn't?
@gavluk To open an image in the Image Editor you need to open ShareX.exe with the -ImageEditor argument, followed by the path to the image.
For example:
[path/to/]ShareX.exe -ImageEditor [path/to/]image.png
On Windows 10, to have a "Send To Image Editor" option in the context menu when you right-click a file, create a registry entry with the code below.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell\Send To Image Editor]
[HKEY_CLASSES_ROOT\*\shell\Send To Image Editor\command]
@="\"C:\\Program Files\\ShareX\\ShareX.exe\" -ImageEditor \"%1\""
Adjust the path to ShareX.exe if needed.
Save the code as a .reg file, and double click it to add the registry entry.
I know this is marked as closed, but I agree that the "Open with -> ShareX" menu setting it to auto upload is a very strange behaviour.
I would expect it to open the Annotation Editor.
