Ralf, I'd like to point out a couple of suggestions on posting photos. Please don't take them as insults, I only mean to be constructive.
Very large images inserted into the text make it difficult to read through a thread, especially when a message is quoted and multiple copies accumulate. [They can be edited out of replies if the replier wishes] Second, when such images are linked off-site, from a German site in your case, they may not be visible to everyone. I can't see your photos when I'm reading threads on my work computer during my lunch break. Your site is blocked by our network. Lastly, images linked from other sites may disappear if that site experiences an outage or shuts down permanently. The images are then lost and the thread may become useless to future readers. Same with posting links to ebay auctions, etc. - they disappear over time and that information is lost.
To make the images as permanent as possible (as long as CMF itself is around), they can be uploaded as attachments to the posting, in which case they will appear in thumbnail version at the end of the image. Or, if photos are needed inside the image, they can first be uploaded to a member gallery and linked from there. Very large images can still be unwieldy, but they will be as permanent as possible.
I do not represent official CMF policy in any way, these are simply my opinions and suggestions as a common user. And if all of this is explained in a FAQ somewhere, I apologize for the duplication of effort
And if my suggestions are out of line or contrary to official policy, I apologize profusely and blame it on my cat who was walking on my keyboard.
