Content/Image sizes in moodle

Hi,

I'm comletely new to creating content with h5p, so I apologize in advance if this is a question whose answer is obvious ;)

We want to use h5p to create content in moodle and therefore installed the corresponding plugins to create the content directly IN moodle.

I tried several activities for images (Image Juxtaposition, Slider,...) and the problem is, that I could't find any option to set the size of e.g. the slider or the frame for the juxtaposition pictures. The images are shown really big and responsive, but, actually, I want them to be displayed smaller.

The reason why this is important is, that we will need these activities mainly for activities showing screenshots of a software. Since some windows of the software are small, I am not even able to get the pictures in a resolution, that still looks good in the size they are displayed by h5p in moodle.... The result is blurred and pixelated images.

So, where can I set the size for the conent in moodle?

Thank you for your help in advance.
