Thanks for your report! Can you send me that image so I can test it?

[sparkwenc]

Indeed, every image here. It seems not a problem on your end, should I reinstall it?

[sparkwenc]

Here is one example

[sparkwenc]

Ok, I found the incompatibility here:

Actually, I changed the theme file, with the default theme Catpuccin, everything is fine.

Now I customized it by commenting all its settings about background color as follows

# ========= Background (bg) =========
#full_screen_bg = "#1e1e2e"
#file_panel_bg = "#1e1e2e"
#sidebar_bg = "#1e1e2e"
#footer_bg = "#1e1e2e"
#modal_bg = "#1e1e2e"

Now get back to image preview spf will crash.

[sparkwenc]

OK! I get that the transparency should be set in config.toml rather than customize the theme file by removing the background color setting. So my own problem is resolved.

But removing the background color setting resulting in crashing when previewing image may still be a minor bug

[yorukot]

Got it, thanks for you debug!
