First, i know this topic has already discussed before, but i didn't find a solution so i try it again !
I tried to change the hotglue pistol with a .png image.
I followed the recommendations by Danja Vasiliev :
Create a square PNG image, don't make it too big, 96x96px is enough!
Upload the image to your Hotglue page (drag it over!)
Select the image and click on the target icon left of the image and copy the value (eg "start.head.147613886210")
Open 'code' page of your site https://yoursite.hotglue.me/?code28, and paste the following code into the field: replacing 'start.head.147613886210' with the value you copied earlier
Done! Shift+Reload your site to see the icon.
But it doesn't work. And yes, i'm using Chrome too...
I tried this code for the invisible logo, and it's working very well :
Do you have some new tips / codes to add my own image as favicon ?
Have a great day, and thank you in advance
