Because of server space.
Let me make sure I understand what you mean by "Post Routes", do you mean attach a gpx or itn file for others to download?
Perhaps we should get more server space? It might mean that a contribution to this site will be required but I think it will be worth it.
.....but what is wrong with doing it the easy (and free) way Tom. You seem to have a bee in your bonnet about this and I don't understand why.
We could post photos too, but the answer is the same; it eats disk space and that costs money and on the server, it costs a disproportionate amount of money. I can buy many Gb of space on a USB drive for a few pounds, but on the server, anyone's server, it costs a huge amount of money.
Cloud drives, llike Google and Photobucket and Microwotsit, are virtually free and will never get full.
No matter how much disk space we 'buy' on the server (which means all members pay more) we will eventually fill it and have to buy more, whereas with a cloud drive of Gb proportions, we may never ever fill it up, try as we might.
Let me know if you have a particular problem with this, because to me it seems to be totally illogical.
I have 100's of photos on my Photobucket drive and from memory I have used 2% in the last 4 years. If I had to buy server disk space to host that amount, it would cost me £200 per year thereabouts.
