Then it must be a big size. You can resize the image PicResize - Crop, Resize, Edit images online for free! here which I prefer or change "Maximum profile photo storage size" from the group settings. 

Hello. In admincp/users/groups/social you need to change the file size in all groups.

^ this will be where your issues is

Thank you everyone
