I was uploading some pictures to post on a build blog, when the pics are uploaded there is a question mark in the thumbnail (no image), I can not see the pic before I post it.
There is also a red symbol in the right corner of the upload window.

Also, How do I delete a uploaded (but not posted) photo? I can highlight a photo but no option to delete it only to post it.

Thanks, I'm new to this format

Godspeed
