What are the Google Display ads images requirements?

[Jameslap]

Hello,

My website logo not accepted for my google remarketing ad campaign. I read the online ad requirements & I recreate it to 200 x 200, but still, it's not allowed. The large image that was previously accepted is now showing a yellow triangle. Please help me to fix it.

Thanks

If you are using responsive display ads, the logo should be in the below dimensions.

Your logo should be square (1:1) and should be 128 x 128 or higher. The recommended size for the square logo is 1200 x 1200. For best rendering, it is also recommended to add a landscape (4:1) logo, which should be 512 x 128 or higher. The recommended size for the landscape logo is 1200 x 300. For all your logos, a transparent background is best, but only if the logo is centered. The file size limit is 5120KB.
