old, but valid nonetheless.
uploaded/attached (NOT linked) images. define board output parameters, reduce the output quality of images displayed through the dojo frontend. (ie: if the defaults are 150x by 150y for an avatar, shave a third off that, and the amount of bandwidth usage reduction will show on the tariff.
uploaded/attached images will try the network too, especially the more viewing, or visiting.
externally linked images/items need not apply, dojo isn't handling those items, or allocating bandwidth, because the sites linked from do it on their tab.
efficiency is the name of the game.
users no longer existent (still on db/banned) that have avatars and customization specific to dojo are still accounted for on the tally up.
removing the banned users customizations will help, and how many B&-&-V& users in the records?!
for what this is worth?!
carry on!
