[TW5] HowTo display image dynamically

[magev958]

Hi all

I have a public Dropbox-folder with a bunch of images that I like to show based on title in all tiddler tagged "Tag1" in my TW5.

 

E.g.

<img src="https://dl.dropboxusercontent.com/MyFolder/[[currentTitle]]" />

 

I guess i need some kind of macro, but I can't figure out how to do it

Presumably, the problem lies in how dropbox changed access to subfolders (for free accounts).
There was a time when you could access those in your public folder via relative paths.
For some long-time users, like me, that is still working.
These days you need to get the public link for each file. :-(

Perhaps take a look at Photobucket, unless you have some semi-private images you don't want hosted.
This works well in combination with...

ximg @ tb5

I'm too is a long term user of Dropbox and is so lucky to have the relative-path-folders :)

Hi again,

Didn't look close enough at your syntax.

What you probably need to use is a (preferably global) helper macro;

along with the macrocall widget to have your parameters evaluated.

Something along the lines of... (untested)

\define dropbox(folder,file)
<img src="https://dl.dropboxusercontent.com/$folder$/$file$" />
\end

<$macrocall $name="dropbox" folder="foo" file={{!!title}}/>

Best wishes,

Thank You, it works perfectly! :)

I used this macro in TW 5.1.9 on Tiddlyspot but it does not seem to work in TW 5.1.11. Has something changed and how can I edit my macro to work again?

\define dropbox(folder,file)
<img src="https://dl.dropboxusercontent.com/u/955759/$folder$/$file$.jpg" />
\end

<$list filter="[is[current]tag[species]]">
  <div class="bigger_image">
    <$macrocall $name="dropbox" folder="Orchidelirium" file={{!!title}}/>
  </div>
</$list>

I don't know if this i relevant or helpful but pancake.io lets you use dropbox as a static server site again.

That might be very interesting, I'll check it out, thanks :)

Hi Magev958

I don’t think there have been any changes to the core that would prevent that code from working. Perhaps the Dropbox URI has changed?

Best wishes
