I am having a problem with the display of images for anonymous users. Logged in users see all images on the site. Anonymous users briefly see images that were uploaded through the Drupal filesystem and placed with img_assist. Using either HTML Tag or Filter Tag with img_assist does not change anything. The thumbnails flash briefly in the spot they were placed by img_assist code, then they disappear, the block outlined for the image collapses, the text fills that space in, and a small dark vertical black line about one row of text high is left in the spot where the image was. That little black line can be clicked on which links to the image node. The large image loads, and then disappears just like the thumbnail.
I tried to hunt down a solution on Drupal.org, and there were similar issues, but none helped resolve this problem.
Access Controls enabled for anonymous users:
node module: access content
upload module: view uploaded files
image module: view original images
Per this message http://drupal.org/node/66760, Input Filter for Inline Images is enabled for each Input Format. I tried ordering the filters in each combination. Also, I have no richtext formatting features installed, though I do have BBCode installed and turning off that module does not help.
This image dispaly problem doesn't generate any watchdog entries.
