Get supported image extensions

(): string[]

Returns a list of supported image extensions. Flmngr will display their previews in the list and provide tools for editing some of them (obviously, editing of svg is not available, and editing gif will remove all frames from the second if the GIF has animation).

The current list of such extensions is: ['png', 'jpeg', 'jpg', 'webp', 'svg', 'gif', 'bmp'], but it may be extended in the future.
