Many people have had some confusion over how to make your images seen in a forum post. Basically there are two ways to attach files to a forum post.
1 - Use the "Insert Image" button (camera icon). Images will be visible in the body of your forum post.
2 - Use the "Attach File(s)" button. Normally used for documents you would like to attach with a post, like PDFs etc. The attached files itself will not be visible, only the link to the attached file.
One further comment. If you're uploading your images directly to Volks Culture (as opposed to linking from Photobucket or Flickr etc.), I'd encourage you to resize them to a practical size. Essentially, we offer convenient hosting of your images, as a free service, but we'll run out of space very quickly if everyone is uploading images of over 1 MB.
If you have larger images to resize, there are a number of free online services such as:: http://www.shrinkpictures.com/
