I'm having trouble inserting pictures from my desktop. I can get them into the Media Library, but they don't insert into my Posts when I hit Insert into Post. Oftentimes, eventually the picture will appear in the Post, but only after several hours. I use a Mac. When my friend does the same operation from the back end on his PC, the process works instantly, every time. Does anyone know what's up? This problem may be related to the extreme slowness of many WordPress functions (edit - delete - etc.) on my computer. In every other respect, I have a very fast computer, except with WordPress. Thanks for any help anyone can offer.
