I understand some people might be under the impression they don't want to abuse the resources here but I have a lot of excessive bandwidth and disk space so feel free to upload your pictures here. You can even hot link them on other sites.
The main reason I like to see them uploaded here is I want to maintain the most concise archive as possible. If they are uploaded here they will be here forever. When other sites are used they have a tendency to disappear over time and when they are used in posts you can really screw up the continuity of the post if the images are no longer available..
