Might be the type? All my fruit trees are on dwarf rooting stock so I can reach the fruit (and the dogs can too of course
)
As to photos the limit is 2 megabytes per photo, with a total of about four mb if you post more than one.
So you need to reduce the size before posting - open in an image programme (like paint) by taking it in from the corners (pic one I, dragged in from the right to hide my address on Smallholding Scotland OSCR page )to remove a bit of the surround - or by resizing, pic two is a screen shot of the drop down menu for resize - try it at 50% and check the size after saving
