Using Premium Doodle Business/Enterprise you can brand your Doodle page (MeetMe and polls) with your own logo, banner(s), a background image or background color. Example here.
If you are using Premium Private you would need to upgrade to Premium Business for 1 or more users in order to brand Doodle (you would only pay the difference – your remaining active Premium Private subscription will be deducted from the new Premium Business subscription price).
The branding you set up in your Doodle account is shown on all your polls, on the poll creation page and on your MeetMe page. It is not possible to brand your polls and/or MeetMe page differently. Any branding change you are going to make will affect both new polls and existing Premium polls. If you need different branding (e. g. for different polls) you would need more than one Premium Business/Enterprise subscription.
Setting up the branding of Premium Doodle
Log in to your Doodle account and open the Account settings in the menu revealed by clicking your name.
Instead of using a large full-screen background image you can use a small one as a pattern. Simply upload the small background image and click "Tile background image".
If you upload a background image with transparency, remember to set the desired background color as well.
If you want to delete an image, click on the recycle bin icon.
And remember to click Save once you are finished. As you do not see the branding on the settings page, please go to a poll or the create poll page to see how the branding looks.
Branding example here. A full-size background image and logo is used.
Use RGB, 72 dpi images and save them as png, jpg or gif. With png or gif, you can use transparency.
The maximum size defines the full size available for the logo and background image. Be sure to scale the images to the according to a max. size before uploading them. Of course, you can also use smaller ones.
Logo: maximum size 300 x 100 pixels, 1 MB
Background image: maximum size 2048 x 1536 pixels, 1 MB
