I have not used those scripts enough to offer any suggestions there. I know with Visual Litebox it is extremely easy to set that up. You may want to email the author of Colorbox directly. He posted his email address on is website: jack@colorpowered.com

Visual Lightbox2 is way easier to use than Colorbox is any day of the week. I'm not sure why you are hesitant to use it, but it's very similar in it's setup as CC's programs are. Set it up totally in the program, it then offers to insert the code for you which you cannot do with VSD, but also gives you the code to enter yourself. It then creates all the files for you and tells you exactly where to upload them. No external settings are needed, all images for arrows etc. are all part of what it gives you for the files you don't have to figure any of it out yourself. It can't get any easier than that. Just sayin'...

Using Visual Litebox, it took me about 3 minutes to set it up with VSD. Here is what I just tossed together quickly:

Thanks for the help everyone The reason I'm hesitant about the Visual Lightbox is the link on the bottom that shows "visuallightbox.com" so it's not as professional. Plus, I feel like I should be able to figure out the other way since I was so close, but I probably will end up just using the Visual one.

That is only because of the trial mode. When you purchase the software, that is removed.

I bet on the trial version there is some code in there which will also make it show up in search results, they like their free advertising.

seen this with lots of trial programs, nothing is free unless it says CC free stuff on it

Considering it's such a small little thing (tiny link on the corner of each image) it's not really that unprofessional at all, but the paid version doesn't have that. If it's only for this one site you'll use it then it's only $49 which is pretty reasonable or $69 for unlimited sites to use it on which is very reasonable.

Free has to get paid for somehow right? Small ads are a pretty small price to pay for free. The big thing here is that you can use it. If it's easy enough to use, then it may be worth either the tiny little ad or the cost to register it.

You can also peruse the code and remove the ad should you choose to do so, but I won't delve into how that can be done, nor should anyone else Suffice it to say it "can" be done.

It can be removed but I'm not going to tell anybody. I don't use it.

My friends photography site that he put a portfolio on using a free copy of photogallery program threw up an interesting google seach some months later

Website is called sensationalyou

the google search result was something like

Sensationalyou Marlow based glamour photograph......js player free photogallery free downloads

Personally as a potential client that search result to me said, cheap photographer not willing to pay for software, avoid like the plague

he paid for the program, and a whole new google search appeared

Thanks all for your help I was about to buy the Visual Lightbox, but did a little more research and found the problem (with the help of http://lokeshdhakar.com/forums/index.php?p=/discussion/5928/prev-and-next-icons-not-showing-upnot-working/p1)

My html WAS:
<a href="image1.png" rel="lightbox"><img src="image1thumb.png" /><a/>
<a href="image2.png" rel="lightbox"><img src="image2thumb.png" /><a/>

Changed to:
<a href="image1.png" rel="lightbox[set1]"><img src="image1thumb.png" /><a/>
<a href="image2.png" rel="lightbox[set1]"><img src="image2thumb.png" /><a/>

And now it works. Have no idea why the [set1] makes it work or how, but it does!
