mmm-instagram: How to resize the Image-Size (instaMaxWidth) ?

[apex4all]

Hey guys,

since a few days i try to change the size of my shown Instagram-Account.

So, at first i have changed the instaMaxWidht and -Height in config.js. If i set the values absolute from 300px to 100px it get smaller but if i set the values >300px nothing happens.

Next step was, to change the values in the json-file in the module folder. I set it to 1200x1200px but nothing happens too.

Have anyone some ideas how i can manage my problem or now, if its limited because of some reasons?

Lot of thanks ahead…
