How you upload images to Amazon

[Jhonsteere]

hello, i wanted to ask a question, what is the best way to upload images to Amazon. i worry about it as i have 1000+ products which all has image or two for them.
I think i should host it from my main pc somewhere as i use dongle connections and they are limited to max 4gb/month.

can someone brighten it up for me how all the image adding process works ?

P.S. never had amazons acc before
