Joomla! Template Thematic PT - Item Support

Hello AS team,

I tried to use the responsive version of the template, but I'm having problems with regular images in articles. The dimension settings of an image work perfectly fine in the administration section, but have no effect in the real site. There, all images are shown with 100% width.
In the non-responsive version everything works as expected.
I'm using Joomla 2.5 with the T3 framework that's being shipped with the template.

Thanks for your help
Hello AS Team,

The site is not public yet, so I can't really give you access to it directly, sorry, but if you could tell me which details you need and where to find them, I'll post them here or send them to you via email. The template used is the responsive version of the Thematic template, the article is just a normal article with an included image (png). What I figured so far is that this happens only to regular articles, as soon as I use K2 content, the images appear as expected. Is using K2 mandatory for the template?

Thanks again for your help.
