Probably are !! There is a size limit per post so if one pic is oversized it takes up all the space !! Look at the bottom when you post a pic where it says attach, below that gives the size and type of files you can use !! One pic is 3000kb but you can post up to 4 pics as long as the size of all combined does not exceed 4000kb !! So you can do 4 pics at 1000kb each !! Or 2 at 2000kb ect ect !!
