What are images on our platform?

Your platform allows visual customization through images or designed graphics. These visuals enhance user engagement and provide a professional and branded look.

Here are the primary places where images are used:

  • Homepage banner

  • Project or folder card (visible on the homepage or within folders)

  • Project or folder banner ("header image" in the settings, appears at the top of the project/folder page)

  • Input (idea) card (shown above individual inputs or in input overviews)

  • Logo

  • In-text images

  • Proposals

  • Event cards

What are the image file requirements?

To maintain clarity:

  • Use PNG or JPG formats

  • File size must not exceed 10 MB

  • Use a resolution of at least 72 dpi (dots per inch)

A higher dpi ensures your image appears crisp and not pixelated.

What are the requirements for attachments on the platform?

  • Each file (e.g., image, PDF) can be up to 50 MB

  • No limit to the number of attachments per project

  • However, uploading many large files can slow down performance

Important: Attached files are automatically downloaded when clicked.

If you want the file to open in a new tab, use the hyperlink tool to insert a direct URL to the file hosted online.

What are the recommended dimensions for different images on the platform?

Homepage banner

  • Recommended dimensions: 1440 × 480 px

  • Aspect ratio: 3:1

  • On mobile: typically displays closer to 1:1

  • Note: You can choose different banner styles (see section 4)

Project/folder card

  • Dimensions: 1400 × 1050 px

  • Aspect ratio: 4:3

  • Maintains 4:3 ratio on mobile

Project/folder banner

  • Dimensions: 1800 × 600 px

  • Aspect ratio: 4:1

  • On mobile: crops to approx. 3:1

Input (idea) card

  • Dimensions: 1024 × 1024 px

  • Aspect ratio: 1:1

  • On mobile: crops to 2:1 or 3:1

Logo

  • Minimum height: 48px

  • Recommended ratio: 2:1

  • Displayed in the top-left corner of the navigation menu

Proposal card

  • Dimensions: 1000 × 500 px

  • Ratio: 2:1

  • Displayed on the proposal overview page

Event card

  • Dimensions: 1800 × 600 px

  • Ratio: 3:1

  • Displayed at the bottom of project pages and under the "Events" tab

In-text images

  • Can be added in project/phase descriptions or surveys

  • Titles are mandatory for accessibility

  • Resizable in regular text fields but not in content builders (see section 8)

What are the different homepage banner display options?

You can choose between 3 layout options for your homepage banner:

Full-width banner

  • Offers the most visual impact

  • Crops the image the most

  • Best for abstract, decorative visuals without text

Two-row banner

  • Title, subtitle, and button appear below the image

  • Useful if your image doesn’t pair well with overlaid text

Fixed-ratio banner

  • Recommended ratio: 3:1

  • Maintains a consistent display area

  • When uploading, you can drag the image to choose which part stays visible

Regardless of layout, avoid using text inside the image, as it may get cropped on smaller screens.

How to resize images on the platform?

  • In regular text boxes, you can resize by dragging the image corners.

  • In content builder areas (e.g., homepage builder, project description), resizing is not possible this way, images retain their original size.

Workaround for content builders:

Use columns within columns to visually reduce image size.
