Seem to be making a bit of a Horlics out of this.
'orrible 'orrocks strikes again! Beautiful photos Hootatder. I've taken one of yours and modded it for easier posting, and couldn't resist balancing up the colour too. Here's your original:
Here it is again, this time
--reduced to a screen res of of 72dpi in both directions
--set to 800 pixels long in the longest direct with proportional scaling on
--the standard colour balance of the app clicked (GraphicConverter, highly recommended, very cheap, lot easier than Photoshop for non-professional to work in)
--saved at 90% quality rating (you can't see the difference even if you're an expert) to save some kilobytes.
Two of these per post should give the software no hassle; I've on occasion sent more per post without hassle. It's a little smaller physically but the forum software won't cut it off at the right, or present it at an odd size, and the clarity of the photo is enhanced, and the actual image requires a little less storage, and is rewritten into standard web format with excess code stripped off.
When the software claims it posted a message it rejected that you are posting again, just add XXX at the end and post again.
Jags will fill you in on anything I missed out.
