问题
I have searched around online about feed images to your rss feed. it seems not very popular. is it correct to use to feed images?
for instance,
<enclosure url="http://images.productserve.com/thumb/547/680654.jpg" type="image/jpeg" length="3241"/>
what is the length in the enclosure elementy?
回答1:
The enclosure tag is pretty popular for things like podcasts (so, audio files) but I haven't seen it used for images often.
length describes the file size in bytes, so it's up to you to pragmatically get that for each image you attach.
