Hello

I am pretty new to TiddlyWiki and wondered it I could get some help creating tiddlers with HEIC/HEIF external images.

I am using Tiddly Desktop and am comfortable manually creating external JPG images as described here: https://tiddlywiki.com/static/ExternalImages.html

I have now come across HEIC images that I wish to link, I understand they are supported by TiddlyWiki but I just cannot figure out how to create image tiddlers without a 'image/HEIC' tiddler type available.

Is there any way of linking external images that are HEIC or will I just have to convert all of the images to JPG??

Cheers.

Although TW5 understands the file extensions and mime types for HEIC/HEIF images, it doesn’t take any special steps to display them, so it is dependent on the browser supporting them. I don’t think Chrome can display HEIC/HEIF images directly. Safari on macOS or iOS does support displaying HEIC/HEIF images.

Best wishes

Jeremy

Cheers.

Thanks Jeremy.

I wonder what are the most practical steps moving forward?

I am using TW5 as a local personal wiki.

So, I wonder would it be more practical to convert images to JPG and then link?

Or..

Is there a way to get Tiddlydesktop to display through Safari so I do not have to convert? (I am using macOS)

Any help would be greatly appreciated.

Have a look to see if there are addons to your prefered browser that enable display of these alternative format images. This is a very common way to add support for different types to a browser. After all PDF and other readers do this all the time. Hopefully then tiddlywikis presentation of those files will result in them displaying inline in the browser.
