i usually use clubsnap gallery to share photos which i have taken (for all clubsnappers to browse). can also link these pics if you would like to share on the "photo galleries" threads i the forum. (storage 5mb limit, 100K per pic - i think)
i also use photobucket, but this is more of hosting adhoc pics for B&S thread, etc. (e.g. pics of items for sale, etc) as it is not as easily accessiable for others to view your photos, but possible to link the pics to share on the "photo galleries" threads as well. (storage unlimited, 200k per pic - i think)
this is not official protocol, just how i use them... yes, both free and compatible with CS!!! :thumbsup:
