We are trying to submit our first application in the Seller’s lounge but seeing the following error: “Upload 400 x 400 pixels and greater icons only” This feels contradictory to the appinfo.json instructions for `icon` to be 80x80 pixels in PNG format. Not sure how to get around this. ---

80x80 icon file is for app testing, and 400x400 icon file is for LG Content Store. However, both files are required for app submission. (See [App Resources](https://webostv.developer.lge.com/develop/getting-started/app-resources#app-icons) and [appinfo.json](https://webostv.developer.lge.com/develop/references/appinfo-json#icon).) Thank you. ---

LG has supplied contradictory info in this regard. This webpage says 126x126: > **[Icon](https://webostv.developer.lge.com/develop/guides/icon#)** > > webOS TV iconography guidelines to help you design appropriate icons for your app This webpage says 80x80 and 130x130: > **[appinfo.json metadata](https://webostv.developer.lge.com/develop/references/appinfo-json#icon)** > > Understand how web apps for webOS TV can manage app metadata using appinfo.json, and an in-depth look at appinfo.json properties that apps can use. ---

126x126 is the Home screen panel size for app icons. Thank you. ---

Is that the icon or the ‘large icon’ ? ---

The largeIcon property is optional. No need to worry about the panel size, etc. As mentioned in the [icon](https://webostv.developer.lge.com/develop/references/appinfo-json#icon) property, 80x80 and 400x400 icon files are mandatory and will be resized automatically before use. Thank you. ---

So then the 400x400 icon file is used for the 126x126 Home Screen panel app icon you mention? How else could a 126x126 icon be filled with a 80x80 image? ---

The icon docs are very unclear. LG mentions three different pixel sizes just [here](https://webostv.developer.lge.com/develop/guides/icon#): ![image](https://canada1.discourse-cdn.com/flex030/uploads/webostv/original/1X/9922555f60c96fcf55e8606d59561b10762982c6.jpeg) ---

As mentioned above, 80x80 icon file is for app testing, and 400x400 icon file is for LG Content Store. 400x400 icon file will be resized automatically before use. Thank you. ---

So the 400x400 Content Store icon will be used on the Home Screen at 126x126 ? And the 80x80px icon will be used during testing … at 126x126 px too? ---

if any update to ICON in seller lounge, will trigger new update to end user? for example, removed old logo icon and added new logo icon ---
