It’s possible to receive the ISS SSTV signal by using the WebSDR at the Goonhilly Earth Station, the audio can then be fed into your PC or Smartphone SSTV App https://vhf-goonhilly.batc.org.uk/
Follow @ARISS_intl on X for official updates, since changes can occur.
Reminder, the images are sent on a (roughly) 2 minutes on, 2 minutes off schedule. So if you don’t hear anything, give it 2 minutes!
Many FM rigs can be switched been wide and narrow deviation FM filters. For best results you should select the filter for wider deviation FM. Handhelds generally have a single wide filter fitted as standard.
You can get predictions for the ISS pass times at https://www.amsat.org/track/
