Question Image are fixed width too small

First of all, please read K 1.5.x Support: Please read this first.

I can't see your forum:

Sounds like a template issue to me. More information required (Kunena version, Kunena template, Joomla site template or access to your site to see the situation for ourselves). Thanks.

Sorry, I just enable the forum again.

Pleas have a look to help me please

Old version of Kunena. What is it: K 1.5.9 or something? Suggest you upgrade to K 1.5.12 and check again. It would help when we ask you questions, like what version, etc., that you provide that information. Thank you.

Your image is too large to display in your forum anyway: width 828 px x 250 px. Images that are too big to fit in the forum are automatically resized (made smaller). Obviously this isn't good enough for your purposes. You either need to make the image smaller (to fit into a 450 px width or you need a wider site template.

Thank you. Now I know How to adjust: Textarea Width to 700px instead of 450px.

Thank you again, You are a man!!!

What version of Kunena are you using?

What Kunena template are you using?

Your current textarea width is about 747 px wide - total width of your Kunena component is limited by your Joomla site template (in your case, it's JA_Vauxite) so it really depends on that. The only settings that I can advise you to investigate are listed in Kunena Configuration ; under "Look and Feel" you might try different values for Textarea Width and Textarea Height.
