One of the features is the possibility to add icons or icon packs in the app to be able to use them. Images can be added in png, jpeg, bmp… but it is advisable to use images in png format to be able to use transparency in the app.
In case you want to add image packs, the format must be a Zip that contains the images in the above format.
The procedure is as simple as going to the add screen in the app, and selecting the image type or image pack.
For association with channels, in the case of m3u lists they must have the name of the images with extension included. For manually added channels, they can be linked directly from the app.
Thanks to the use of OneDrive, the app will synchronize logos and channels between the different devices you have.
