i used to use pixelpost but it was a small hassle to have to bring down resolutions and then upload (as well as uploading full res in flickr)
Last month I switched to blogger,
http://www.hitkaiser.com
And I use flickr to post directly into blogger... So far so good, I dont have to worry about bandwidth issues or renewing hosting etc.. All i pay for is my domain and flickr pro which is well worth it anyway
I would still like my images to appear a big larger though (coming straight out of flickr)
