I have also just had a message pop up saying my startup disk is full. How can I manage all my files... as they seem to be everywhere... to my network drive?
Be gentle... I am new to Mac.
To be honest...this has nothing to do with the computer being a Mac...it's more about having an organization/storage strategy.
As chscag mentioned...installing a larger SSD would help (if it is possible with this computer). Some Apple laptops are harder to do upgrades on. But a larger SSD will be expensive...and even if you installed a 500gig SSD...it sounds like you will eventually run out of space on it as well (if you point & click...point & click...point & click...and save every photo you take).
The external storage idea is certainly more cost effective (cost/gig of storage)...and certainly more expandable (could have multiple drives).
An internal 128gig SSD is pretty small for most folks. So an internal SSD upgrade would probably be nice for just about any reason...not just photo storage. But again...this depends on what model MacBook Pro you have.
Bottom line...you need to develop a storage/organization plan that works for you...and stick to that plan...so that things stay organized...and don't have photos "everywhere"!
Do I have all of my computer stuff as well-organised as I would like??...no. But I also do not have that much to organize (I would probably be in great shape with just a 128gig SSD).

p.s. Another idea is storing all of your photos online (in the cloud) with one of the online storage websites. Of course you would have to look into the costs...to see if this would work for you.
