3 Steps to your WordPress Photoblog

Why another photoblog system?

There aren’t many open source photoblog systems out there in the wild. I searched a long time and found only few. Evaluated all of them and decided to program one on myself, since none of them met my demands. I did that about three times – Every version was build up from the scratch. Every version was better and much more flexible. More cool and finally more proprietary.

Every time i saw a feature in another blog system that i wanted to have – i had to spend much of my rare spare time to design, program and integrate it into my own photoblog system. After implementing some features like captcha, ping and trackback, etc. etc. i decided that this was just a waste of time.

There already was a system out there having lot’s of features and a huge community: WordPress. Yapb is my try to build on a wide spread platform – And to get what i want – As a photographer and programmer.

Why not use services like Flickr, Deviantart, etc. etc. ?

Why hazzle with renting a suitable webhost, installing a photoblog software, configuring the whole stuff, eventually solve problems, searching and installing a cool theme, etc. etc. – If i can have it all (and more) with one click at Flickr, Deviantart, etc. etc. ?

I’m only able to give you a hint on my opinion why i don’t want to host my images on such a service. Fortunately, for the impatient among us, it can be told with only three (and a half) words:

It’s my image.

Post your image on a foreign server and you’ll never be exactly sure what rights you have on your own images until you’re a better laywer than the one hired by your prefered photo community. One nice example: Flickr was sold to Yahoo AFTER they had tens of thousands users and hosted millions of images. If you’re posting images to flickr right now – Do you EXACTLY know, what rights Yahoo currently owns on YOUR images?

If this is perfectly ok for you – Go on and use those communities! After givin away your personal data, you will have an account for free and no hazzle with setting up your own photoblog. There are thousands of users just waiting for you!

Technically spoken

Yapb integrates tightly into wordpress. Via Javascript DOM manipulation it injects several form additions into the standard wordpress post form. It provides additional data and functions to themes so that nearly every theme can be converted to a photoblog in virtually no time. Yapb doesn’t touch original wordpress code – It’s using it.

Support YAPB

Do you like YAPB? Do you use it regulary to show your photos or images? Did YAPB save you time? Or you just want to give something back for the time spent to create, maintain and support YAPB? Just Donate a little ammount so i may buy a good book, DVD, etc. or just pay some server traffic. Bigger ammounts (if any) will be invested in my photo equipment of course ;-)

    It doesn't work at all for me. Wordpress 2.7. And I've done everything right. The image I uploaded was just shown as a red cross, the image wasn't found. But it was uploaded. So, what's wrong? :S

    I installed this, and I think you have built it backwards.
    What I am looking for is a plugin which does the following.
    Hooks onto the media library upload function, following the upload of an image by adding the URL of the uploaded picture into a post template, and to publish a new post with each new photo uploaded to the media library. Exif data should be handled too, and placed into the template, as required by user. Tagging can be auto via exif. Who wants to manually write a new post, upload their image and tag is manually everythime they publish a photo!?!

    Finally, Johannes. I'm so glad that you're also one of the people on this planet that isn't stupid enough to use Flickr of Deviant art. I don't want some corporate claiming the rights to manipulate and use my work without asking. Thanks for an awesome plugin. I going to definitely link bag to you on my site.

    I get the following message on my wordpress dashboard :

    Could not create YAPB Cache directory automatically.
    Please create /f1/content/myachingheart/public/wp-content/yapb_cache/ manually. Don't forget to set the according directory permissions to 777 or 775.

    Can someone please explain what I do with this, where I put it?


    thanks for any help here...

      Hi Morris - You have to create this directory via your prefered ftp client because YAPB tries but isn't allowed to do it. The directory (and correctly set permissions) are needed, because YAPB needs a place to save it's generated thumbnails.

    Hi Johannes,

    I'm having the same problem that a number of other people are having...and, so far as I can tell, none of them have been answered yet. (At least not to the degree where it has helped me figure out what I need to do.)

    I'm getting the following message at my WordPress dashboard:
    Configured WordPress upload directory doesn't exist
    Please make sure that the directory exists and is writeable.
    I know how to create a directory. I know how to make it writable. I don't know where to put it. I've tried to place it in a variety of different locations...and I still get the same message at my dashboard.

    As part of my own research, I located this url:


    While that may no longer be a meaningful link--I don't know, maybe it is--I could tell by the last twenty lines of coding, or so, why I was getting the message from above, but I still have no clue as to how to get rid of it.

    So, if you can, please tell me what I should name this directory, and where--exactly--should it be created?

    Thanks for any suggestions. I've toggled the form to tell me if there are any subsequent responses to this message, and will be ready to furnish you with any additional information as soon as it is requested.

    Hello Johannes et al,

    I have extended the plugin to automatically upload the photo to my flickr stream when publishing the blog entry (at least in a crude way). It seems to be working well thus far. I am passing to flickr the image path, title, and keywords (tags). One thing I have not figured out is how to get the description or caption (i.e., the contents of the edit control under "Upload/Insert"). Is there a way to get this programmatically via the API or one of the objects? Is it stored with the Wordpress object?

    I may be the only one, but I just updated my Firefox browser and now I do not see your plugin.

    Thank you so much for building this plugin. There is a site that has used your plugin with Grain theme.

    this is the link: http://www.camielschoonens.nl/

    I really, really, desperately need to learn how to produce a page just like this one, with thumbnail effect as well as the text effect that pops with a mouse over.

    Is there a clear description and a step by step how to for this? I would be so eternally grateful for your response.

    thanks so much.
