Please describe your problem:

Running pretty much every thing by default mostly.
When trying to post an article with image attachments, say img_1.jpg to img_5.jpg
like inline

img_1.jpg
img_2.jpg
img_3.jpg
img_4.jpg
img_5.jpg

For some reason after posting, the image displayed will be in incorrect order but the code stays the same.

e.g on display

img_2.jpg
img_1.jpg
img_4.jpg
img_5.jpg
img_3.jpg

Already tried applying the known issue update (viewtopic.php?f=556&t=2453611)
on the forum but still no help. Just wonder if anyone else has ran into problem like this?
