Thread:Extension talk:RSS/Will this support the feed's media enclosure?/reply

Yes, the up-to-date version on github https://github.com/Wikinaut/mediawiki-extension-RSS does support the display of for example images as part of RSS items. (The most recent version is currently hosted on my github repository).

Please carefully set up the parameters of your mediawiki installation and the RSS extension as explained in detail in Extension:RSS.
