Peter Walker, hello!
About folder hooks, its my fault... Your right. This folder must be a subfolder of advprintthread folder. Re-upload mod.

Try to replace file:
/forum/advprintthread/hooks/attachments.php
with file, which attached to my post(this post).

Let me know, please, if its help you.
Thanks!

Thanks, I have exchanged attachments.php (and put hooks in the right place) and the mod is now working. Direct image links and inline attachment images are now displayed correctly in print mode.

Thanks a lot for fixing this so quickly.

I do still have one issue with this mod. In admincp/options, you have changed the colours of the settings page for your mod. While this looks pretty, it unfortunately affects ALL section when you select "Setting Group -- Show All Settings --." Now every section is in this unusual colour and has the title "Wellcome to "Advanced Printthread Pages" setup"
By the way, the title has two typos, it should be ""Welcome to "Advanced Print Thread Pages" setup"

It would be great if you could limit these colours to your section or just leave the standard colours, as every other mod does.

I understand... I will update mod(little later), and I think I'll remove custom style completely.
About typos))) What can I say? Thanks! My English leaves much to be desired... I'll fix this too...

v1.2.0

• Fix bug with custom table prefixes(file attachments.php).
• Removed my custom style for dont change whole admin-cp style while selected: Setting Group / Show All Settings.

(thanks to Peter Walker :) )
