Description Stefan Paul 2021-06-21 12:31:18 UTC 
SUMMARY
we're using digikam on several computers with Windows 10 & macOS BigSur, with a central database & storing location on a NAS.
digikam version 7.2
My Problem is now, that we would like to use our own tag-symbols.
When we take one from the system-symbols, everything woarks fine, it changes on Windows & Mac, regardless of the computer or operating system on which the change takes place.
When I try to change it on the macOS and I go over "other symbols" & choose, the Finder opens, but I can't choose anything and digikam blocks completly, I have to close the windows over the cancel buttons, and somethimes digikam crashes completly.
When I do the same thing on a Windows PC, after clicking other symobols, a window opens with the path C:\Programm Files\digikam\bin. I can put there my .png symbol and I can use it as I like. But when I now open digikam on macOS, digikam noticed that the symbol has changed, but does not find it, and thus does not show a tag symbol at all.
My question now is, where can I save tag symbols so that I can use them under both windows and macOS

Comment 1 Maik Qualmann 2021-06-21 16:45:52 UTC 
The crash of the symbol dialog is known, but the problem is due to a KF5 component that we use and does not work correctly under MacOS.
The symbols / images should be part of the collection. Then the image must be drag&drop onto the tag and set as a preview.

Comment 2 Stefan Paul 2021-06-22 06:24:22 UTC 
Thx Maik for your response.
Is there a possibility to put images/symbols outside digikam into the collection ? Where are they saved on macOS ? Which size should they have ?

Best regards,

Stefan

Hi Stefan,

Usually tags thumbnails are icons, with a max size of 256x256. No need more.

You can register a dedicate collection in the digiKam database storing all your files that you needs. Using PNG format will be the best choice, but it's not necessary. WebP for ex must work as expected with better size compression ratio that PNG due to use wavelets compression.

Q: did you try the last 8.0.0 release ?

Best regards

The solution listed in comment #3 must be enough. I close this file now.
