Hi,

I am trying to get the source for an external image from a tiddler field.

After unsuccessfully testing both the img declaration ([img[source={!!myfield}}]) and the image widget (<$image source={{!!myfield}/>), I also tried using a macro to output those statements, or just to take the field and output the source, with no luck either.

Does anyone knows how to do this, or if it is possible at all?

Regards,

Marcio.

I couldn't get the img version to work but the image widget should work, you are missing a } in it.

<$image source={{!!my_field}}/>

works for me when I put https://upload.wikimedia.org/wikipedia/commons/thumb/a/ae/Indonesia_-_Lake_Toba_%2826224127503%29.jpg/1280px-Indonesia_-_Lake_Toba_%2826224127503%29.jpg into my_field.

I don't think that the img shorthand works with text references. This works

[img[https://upload.wikimedia.org/wikipedia/commons/thumb/a/ae/Indonesia_-_Lake_Toba_%2826224127503%29.jpg/1280px-Indonesia_-_Lake_Toba_%2826224127503%29.jpg]]

but not this

[img{!!my_field}]

Hi Jed,

Thanks a lot! I couldn't believe I overlooked this missing } all the time!

Regards,

Marcio.

Hi Jed,

Now I am trying to get the source from a combination of a path (output by a macro) and the tiddler field, again with no success testing many different approaches.

Would you have any tips on this?

Regards,

Marcio.

I wrote about concatenating strings here http://inmysocks.tiddlyspot.com/#Concatenating%20text%20to%20make%20dynamic%20URLs

It should cover what you need.

Jed,

Thank you very much, this was very helpful. I added your wiki to my bookmarks to check the rest of the stuff later.

It took some time, though, as I had a third macro which transforms the tiddler field, and I had to experiment for a while until I got it right.

Regards,

Marcio.
