As they are courtesy of BYAP one would assume they had permission, wouldn't one? but obviously they don't, but forums are public domain are they not?, and no one actually holds the copyright for pic's, but bandwith stealing well............I was in the PC game in the late 90's and bandwith was an issue because of Dial Up Modems and also cruel bandwith limits supplied by ISP's, I am sure there is a law in the U.S. to prevent people linking back to your site without permission of the site owner, or was anyhow.
I flicked through a few pic's (sorry about the BW EB) and saw OBO's and Rupe's House my own Blue Marron, Party (another) at BYAP, heaps of pic's of water test results and google sketch drawings,
WTF is the idea behind the site? all the pic's are meaningless without the story, seeing pic's of dead fish is quite boring, so you need the story.

hmmm , pictures of my backyard , and me , taken out of context and thrown up on a random image generator
linked and acknowledged from here or not , Im not sure Im happy with that
especially given that it's called "Aquaponic.org" and doesnt explain ANYTHING , teach anything or even say anything at all ..

Nothing new or illegal about that Boris really, remember Google Street View?
If I knew strangers would be looking at my pic's, I would have cleaned up the yard :shock: :lol:

They haven't asked permission and it links directly to this site for each picture so uses a a fair bit of bandwidth...

Would have been nice if they had asked.

Can you block there IP.
Or at lease put a BYAP.com.au stamp on all the photos. :mrgreen:

I do a ton of web development work (not the fancy page layout stuff, but the behind-the-scenes nasty programming).

The way the pics are stored on this site make them very easy to grab. The problem is that when someone uploads a new image, it gets a unique identifier (UID) in the site's database. Unfortunately, this UID is being sequentially created which makes it easy to just type in an address and grab a photo. Try it out: type in
Code:
http://www.backyardaquaponics.com/forum/download/file.php?id=100
into your browser. Start changing the last number around to different values. Sometimes it's hit-or-miss - values between 1000-2000 work pretty good. When I posted my images, I didn't upload them, instead linked to my picasa account. One of my images is at
Code:
http://lh5.ggpht.com/_Mb8fhw0xAcY/SbwqS2LFTgI/AAAAAAAAAPQ/kGjRHvqh-jA/s400/100_0315.JPG
. You can see that the big string is used to encrypt the name, so it's nearly impossible to guess what other image names are.

They way I block people from grabbing photos from our site is to store the images with additional information in the UID field, like an embedded date code or just some random characters. Our images usually have a 32 character UID....basically impossible to guess what the UID is.

Another way to grab images from a web site is to use a spider. It's a bit more complicated, but it's a good way to grab images that are using encrypted UID's. A spider just will go through the entire web site (just like Google would do) and grab all the content from the page and figure out the name of every image file. The site would then store all theses image names in a database. There are ways to prevent this also, usually with real-time encrypting of the name so that the UID appears to change every time you went to load the page.

Although it's nearly impossible to enforce, here in the US, grabbing images from another site and publishing them as your own is illegal. Publishing them with credit to the original site is a gray area....which Google has battled with for awhile with their Google-Image area and book scanning system. The original creator of the image owns the image, even if they upload the image to a web site (unless the hosting web site posts a message stating that they can take ownership of the image content).

I have posted image links from my system page to outer parts of the forum using the img tag..

I have seen a few webpages that will not display a picture if posted to another site. Perhaps they have a script to check the referrer page and only serve the image if the image the reference came from from the site hosting the image.

How can I prevent people from "stealing" the images from my web site?

The goal here is to prevent people from inlining your images directly from their web site, but accessing them only if they appear inline in your pages.

This can be accomplished with a combination of SetEnvIf and the Deny and Allow directives. However, it is important to understand that any access restriction based on the REFERER header is intrinsically problematic due to the fact that browsers can send an incorrect REFERER, either because they want to circumvent your restriction or simply because they don't send the right thing (or anything at all).

The following configuration will produce the desired effect if the browser passes correct REFERER headers.

SetEnvIf REFERER "www\.mydomain\.com" linked_from_here
SetEnvIf REFERER "^$" linked_from_here

<Directory /www/images>
    Order deny,allow
    Deny from all
    Allow from env=linked_from_here
</Directory>

Further examples can be found in the [url="Environment Variables"]http://httpd.apache.org/docs/1.3/env.html#examples[/url] documentation.

Yes Steem sad but true :lol: But I still don't get the concept behind the site, am I missing something?

I agree, it's just 'so random' to use the favourite new phrase correctly rather to describe everything weird ;-)

I was flipping through them and a shot came up of a girls chest in a blacktanktop that said "I am not Mrs Right but I will F*** you till she arrives". What thread is that in? Had to quickly look behind me as I was at school at the time.

You are right though it is nice to just look at the pictures some time. I often wondered if there was any way of linking all images posted by each user into an album that is linked to their profile. That way you could flick through pictures of a members system to get ideas then go to their system thread to read the details if you need.

I think the old forum had some sort of gallery didn't it?

A gallery for each member might be nice but as long as the forum and sight are working well, I don't want to beg anyone to mess things up.

That random picture site is a bit annoying in that it doesn't give any info. It was probably just some one trying their hand at some web site programing. I just wonder who it really is.
