PROBLEM images and css have text/html content type

[d2a]

Just tried viewing the header via http://www.rexswain.com/httpview.html and the headers are seemingly correct. content-type certainly is. very strange. user agent maybe? anyway...

i'll try to redact my haccess and post here, but i've tried this with a sister site (on the same host) with no htaccess of any kind, and same results - tumblr doesn't accept the image. wish it was a little less obscure...but thanks for your efforts.
