App UI - messageboxes - notify on incorrect extension

Post by user0 »

XnViewMP 1.6.5 64bit
Windows11 (23H2), display resolution 3840x2160, win scaling 150%


App UI - messageboxes
there is no any indication that opened image has incorrect incorrect extension, eg test GIF image has PNG extension
test_img_gif_with_png_ext.zip

Suggestion
  • add new messagebox to
    - notifying user that file extension <> file signature AND
    - offer to rename file extension



Example
  • IrfanView
    msg_rename_extension_irfanview.png
