Please tell me you're testing attachments showing up.
Mine just show as "Attachment XXXXX". Then I can go in an edit my post, delete the first attachment, reattach it, and then it shows exactly like it should.
I'll pm you my login information, and you can try to post in this thread.mine post fine, I can't reproduce the problem.
I guess I'll have to dig into when I get a chance
This option will attempt to automatically resize image attachments that exceed the set dimensions for that specific image type. The image will be proportionately resized to the maximum dimensions for that image type. Resized images will be converted to JPG images to conserve space. Image types that can be resized depends on your server configuration.
