Hello Lena,
I do apologize for the delay in this answer. I looked at it yesterday and it appears my answer did not get saved. If you’re working with an image on a page, if you’re pulling it from media library, there 3 sizes that can be set (thumbnail, medium, large). These settings can be found in settings under Media. If you want to work with different sized images, then you can set the size of the image in BoldGrid using HTML in the image properties. I hope this helps to resolve the image issue. If you have any further questions or comments, please let us know.
Regards, Arnel C
