Change image size and position of images

Hi @irith-herman,

Is there any posibility to make some changes in size 

The size can be changed in the Dashboard > Forums > Settings > Addons > Attachments admin page. Just find and configure the following options:

• Thumbnail Max Width
• Thumbnail Max Height

image position?

Provide us some example URL and let us know what you'll need to change. 

It's not a way for a simple user (not admin or moderator). How a simple user can resize or modify picture position with this addon from the window editor ?
