 * Hi **davisnz**,
 * Thanks for using our plugin.
    Please use **po [1] Full Text** for your **Get 
   Images processor**. If the problem still occurs, please post again here with 
   the link to your RSS source, so that we can check it.
 * Best regards.

 * Thank you so much, I’m going to try it now, I’ve been trying to understand how
   to use the plugin the whole night and it’s a little bit confusing, this is what
   i’m trying to do:
 * Show a thumbnail picture from the post, in the post include 2 or 3 pictures and
   half or the full text. But at the end needs to have the source and the link to
   go to the original post. That’s all i’m looking for, can someone help me please?
   Thanks.

 * Glad that I could help :”)
 * You can watch the showcase video tutorial for WP Pipes in [here](http://wpbriz.com/wordpress-rss-feed-post-using-wp-pipes-minibizweb/)
   to get a clearer image of how to make Pipes work for your benefit.
 * About your specific problem, I nominate the **Cut Introtex Processor** as a solution.
   Please click on the link below to view the field mapping:
    [Fields mapping for introtext with custom length](https://docs.google.com/a/foobla.com/file/d/0B829n4QBUwXdQjhNMjNsWEtBUnc).
 * The **Words** option for **Cut introtext** processor would decide the minimum
   number of words to be cut from **po[2]html**, the returned HTML string will be
   stored in **po[3] introtext**. You can use it for **[di] content** to post with
   a shorter content. Remember to set the value as **YES** for the **Finish Sentence**
   option. You should also check if the **Remove** option in **Get Images** processor
   is set to **Yes**, to ensure that there would be no duplicated images in your
   auto posting.
 * The “link to original source” question has been answered in this thread: [Giving credit to source?](http://wordpress.org/support/topic/giving-credit-to-source).
   Please go there and read. If you still have question, please don’t hesitate to
   ask here again.

 * Alright, thank you so much! That solved my main problem, now the only one that
   i’m getting is that my images are not showing up, not even as a featured image,
   I did all this [https://docs.google.com/file/d/0B829n4QBUwXdQjhNMjNsWEtBUnc/edit](https://docs.google.com/file/d/0B829n4QBUwXdQjhNMjNsWEtBUnc/edit)
   but doesn’t work, can you help me out please?

 * Hi **davisnz**,
 * Can you please export your pipe and upload it here for me to check? You can do
   it by clicking on the small arrow next to the <<**Save**>> button and choose “**
   Export yo .pipe file**“.
 * There are cases that require us to make heavy configuration with Parser Code 
   and the likes before we could make Pipes fetch the content accurately, and it’s
   kind of hard to offer a solution when I have to go blind on the data construction
   on your source.
    Or you can show me the **link to your RSS Feed**.

 * Hi **davisnz**,
 * I’m really sorry but while investigating you source, we’ve found out that their
   images was not displayed with image tags, but with a flash gallery, so it’s pretty
   hard to rip images from them with just standard processor in the free core of
   WP Pipes. Moreover it’s not just flash gallery that they used, sometimes the “
   images” are actually screenshot from a youtube clip.
 * Probably we would need the DOM processor for such a difficult case. If you really
   need it, please check out the [Shop section on our website](http://wpbriz.com/shop/).

 * Okay thats cool, I only need at least a featured image, I don’t really worry 
   about the content, is that possible? I was doing crazy stuff one time and I got
   it, but I wasn’t able to use it because an error, can I put a featured image?
   That will solve everything. Thanks!.

 * Well, I think it’s possible with some post if you use the Parser Code. But since
   the structure change from post to post, you would have to keep a monitor on you
   pipes and re-code it for posts with a different structure, and manually run the
   pipe again.
 * If you don’t mind doing it, I could cook up the Parser Code that would work for
   posts with flash gallery for you. I haven’t look at posts with Youtube thumbnail,
   so for now I really can’t promise.
 * Best regards.

 * Oh dear **davisnz**, I think I have good news for you.
 * I’ve tried this code on our Parser Code simulator and looks like it works for
   both youtube clips and gallery flash:
    `ginner|0|div|cover-wrap|0|1|`
 * You can use it with another Get Fulltext and feed the result to a Get Images 
   processor. Please inform me if it works for your Pipes system. I would be waiting
   for news from you.
 * With best regards.

 * Thanks Coven! I’m going to try it out! Btw I’m sorry for my ignorance, but how
   can do I set up: ginner|0|div|cover-wrap|0|1| ?

 * Dear **davisnz**,
 * I mean you should:
    – Call a Get Fulltext processor **only to get your images**.
   Please use the code I’ve given you for the Parser Code box of this processor.
   It would extract only featured images from the post in your RSS Source. – Then
   use the **fulltext** field produced by the before-mentioned **Get Fulltext** 
   processor as input for your **Get Images** processor.
 * Please view the screenshot in the link below fore more detail. I’ve marked the
   place for your Parser Code and the flow of data from field to field in there:

 * If you still have any question, please feel free to ask :”)
 * With best regards.
