I often see the following error when I'm trying to post some multiline equations:
[LaTeX Error: Image is too big (809x21, limit 600x220)]
Is there a good way to get around it.
Given the height of the picture (21 pixels) I guess you forgot to insert line breaks ("\\") where needed. If that does not solve the problem you will have to split your big equation into smaller ones.
