Cannot see images in articles [Fixed]

I installed Hot App using Hot Start - I created an article but cannot see any images within the article, if I view the source code I can see the link to the images but they are not displayed.

Magic Quotes is off

Sample page here with an image at the top and bottom of the page that do not show

Try turning off all text filters in joomla global configuration

Tried that - made no difference

Modified the article and saved again but images still do not show

Any other suggestions

Are your images visible when you are in article editor and toggle to normal view mode ?

I found the problem due to an entry in the template_css.css as follows:

.content_sparky img {
opacity: 0;
}

So because of that all content images are transparent, they are there but just cannot be seen.

You may need to fix this issue in the template
