Hi @corrag_oslo,
I'm not an HEIC file expert, but I had a few thoughts that you could maybe try. When you read the HEIC file in, can you check the feature information window for those GPS coordinates? I'm expecting you'll find it under heif_exif_gpslongitude and heif_exif_gpslatitude. If they're not already exposed in your table in the Visual Preview, you can use an AttributeExposer. According to the Feature Representation doc, this should come in as degrees minutes seconds, so you could use something like a DecimalDegreesCalculator to convert it and then create points using the VertexCreator. From there you could see how you want to 'attach' the photo. I don't think the shapefile writer supports rasters, so it might be that you could add an attribute with the heic file path perhaps?
Alternatively, to create the points, you could try to make use of the PhotoCoordinateExtractor. It's a linked transformer, but you could right-click it and hit Embed, which will turn the transformer green. Next you can right click it to edit and it'll open up in a new tab. If you wanted to try to get it working for HEIC, you could go through and replace the jpeg attributes with the corresponding heic attributes from the linked Feautre Representation doc and see if that works for you. I'm not 100% sure on this as I haven't tried it on my end, but might be worth exploring!
