Uploading a cover image is something that represents your idea and can contribute to the impact of your entire Fundable profile. You will notice that after uploading your cover image, the builder does not have an option to delete what's been uploaded.
You can only change the cover image by clicking the select image button. A selection dialogue box will pop up and you can choose the new image you want. The changes will automatically save and will reflect immediately once uploaded.
Remember the builder accepts jpg and png files only.
