Logo settings
The Logo settings tab shows your current logo and lets you upload a new one. JPEG or PNG both work, though PNG is usually better for logos. Use as high a quality original as you can, ideally no larger than 400KB.
Favicon
The favicon is the small icon shown next to your page’s title in a browser tab. If you don’t set one, your Artlook logo is used instead. To set your own, upload a JPG or PNG file here — ideally square, and preferably 64x64 pixels.
