1. is there possible to make a link in postpit_legacy Templat like "my Picture" so that in every User Post is a link to the public Picture of this User...

Yes
just do the following
in postpit_legacy
Find

<div>
					$vbphrase[posts]: $post[posts]
				</div>

after it add

 
<br> 
<div><a href="vbimghost.php?do=viewimages&id=$post[userid]">$vbphrase[vbimghost_menushimg] </a> </div>

and it should display what you want

2. take a look http://www.hilfe-forum.eu/vbimghost.php?do=userlist

Picture without Username are from Guests but Guests don't became a link to show here Picture....
Is it possible that Guests make a quick Register only for the VB image Hosting

like here:
PicTransfer.de

i didn't get what you mean
if you want to show a user name guest for people who didn't register
modify the code in vbimghost.php to the follwoing :
in line 239-240
find

 
while($row = $db->fetch_Array($result)){
			$vbimghost['username'] = $row['username'];
			$vbimghost['imgcount'] = $row['imgcnt'];
			$vbimghost['userid']=$row['userid'];
			$vbimghost_usersbit.=eval('$vbimghost_usersbit .= "' . fetch_template('vbimghost_usersbit') . '";');
		}

replace with

 

while($row = $db->fetch_Array($result)){
			$vbimghost['userid']=$row['userid'];
			if ($row['userid'] == 0 ){
				$row['username']=construct_phrase($vbphrase['guest']);
			}
			$vbimghost['username'] = $row['username'];
			$vbimghost['imgcount'] = $row['imgcnt'];
			
			$vbimghost_usersbit.=eval('$vbimghost_usersbit .= "' . fetch_template('vbimghost_usersbit') . '";');
		}

this will be added in the next release

3. Pic host for guests is a top way to Promote a Board.

But it needs that the picture when it post in an other Forum and someone click the Picture that the User see that the Picture is hosting on my Board...
Possible to show the Picture (full size) in a html or php page with Promotion to there Board were the Picture is hosting?

i'll add it to my todo list
