How to add placeholder images from Imageholdr? - image

I am a new developer and i searched for tools that i can use to design websites more efficient, and i came across http://imageholdr.com, anyone used it before? They say that i can add pictures easy on my website without downloading them or so.
I tried to use http://imageholdr.com/500x500 and it worked on my website, but i want to use category and it doesn't work i don't know why can anyone help me setup this? The site instructions are that i must use
http:// imageholdr.com/500x500/category/cars/ but it doesn't work. Any solution? thanks

You misread the instructions. The correct url is just http://imageholdr.com/500x500/cars/.

Joomla SobiPro search results in a 404

(Apologies if I'm breaking any community guidelines here with this question, I just don't know how else to ask?)
I've recently migrated one of my Joomla sites from 2.5 to 3+ and one of the most important components I use on the site is SobiPro.
I've upgraded SobiPro to the latest version as well and made sure that everything is in order.
Now this is where I'm having a problem. On just one single section, when I do a search I get a 404 when going to the results page and for the life of me I don't know what is wrong.
This is not happening on any other section, just this one. I've checked all settings and I've literally run out of ideas as to where to look and what to do to get to the bottom of this.
I'm happy to provide further info, I just don't know what to provide?
Any help that could possibly point me in the right direction would be greatly appreciated.
I have seen this happen in various ways and the fix usually tends to be the following.
Turn "Search Engine Friendly URLs and Use URL Rewriting" off.
Navigate the site on the frontend, to the area affected.
Then turn "Search Engine Friendly URLs and Use URL Rewriting" on.
May need to clear the cache afterwards, and make sure your hosting doesnt have some extended cache on, via php.ini.

How to add new field in checkout that is displayed in order view in backend

I am totally new to Magento. Still learning, so I am confused about where to start off when I have to do something new.
I have to add just another input field in the checkout that gets saved in the order and displayed in the back-end.
So can someone give me directions? It can probably be implemented in an existing extension, but I don’t really have a clue. Any help and explanation will be greatly appreciated.
It would seem a popular solution is to utilize the order "agreements" for comments.
My answer here has lots of tips
And this blog specifically talks about installing a free extension and his explanation of the process is simple and thorough.

Need help creating an RSS feed from Joomla 1.7 site

I'll try to make this clear. I need to make a few pages of my Joomla site into RSS feeds. I don't need the entire site.
I've run into several examples of how to do it, but none of them are really clear. Can anyone PLEASE tell me the easiest, most effective way to do it?
I've never worked with RSS feeds before, so please make it as simple and clear as possible.
I really appreciate it.
Thank you.
To make a feed in Joomla you just make a view.feed.php file that sits next to your view.html.php file. Basically you just follow the model from one of the category feeds. You are using the feed document.

Custom/better magento product landing pages

I tried and searched through some Stackoverflow question and answers but still wasn't able to find my answer. I am hoping this is something simple, but it not I'll give it a try either way. Is there an extension or can I setup product landing pages similar to this in magento? They look really nice and would like to do something similar on my magento site.
Example here: http://gearx.com/snow-sports
Any help or guidance would be great!
Thanks in advance.

Now I am just trying to actually get it to work.

Is there a website that provides code for the Like, Tweet, +1 and Share buttons?

I've found a Wordpress plugin which provides code for all these buttons but I want to put them on my website (which doesn't run Wordpress).
Is there somewhere which provides the code or do I have to do them all separately?
I'm trying to add them to this website: Compress My Code.
There's lots of plug-ins for that available out there if you care to search.
My personal preference is the "SexyBookmarks" which look a bit like this:
And here's how you add them.
I've found this which seems to have everything I need, thanks for the other answer too though :)
